Katie Knight is one of the main protagonists of "Big Time Rush". She is Kendall's little sister. She is intelligent mischievous and a troublemaker at times. Katie enjoys the guy's adventures. She helps the guys she is great at poker and is able to get into Gustavo's head as shown in Big Time Crib. She makes friends with the staff and a lot of the adults but not so much as to kids around her age.
This little bundle of joy is always there to make life exciting for her brother and his friends.
Katie Knight is portrayed by actress Ciara Bravo.
Katie is a classic "little sister". She is smarter than everyone and could easily rule the world one day. Katie is a gifted young girl who always gets her way no matter what or no matter who tries to stand in her way.
Katie is shown to be a lot smarter than not only her mother but most adults often outwitting them (Mr. Bitters and Gustavo are common examples). With her extremely high I.Q. Katie is the smartest person in the entire show.
She enjoys blackmailing she likes to gamble and has got an entire pile of money and a watch while gambling with some Palm Woods employees but her mom stopped her and returned the money and the watch.
Katie goes to the Palm Woods School just like the boys after starring in a commercial where all she had to do was beat up a boy who she pummeled in the audition room. She is also very clever and has excellent business senses - which is why some times the boys need her for their major plans.
She's tougher than any girl and is impossible to put down. Katie has a strong will and is very confident in herself.
Shockingly enough she and Kendall don't fight as much as siblings usually do. In fact she looks at him as a role model. She enjoys video games but really doesn't have any friends her own age but is very charismatic.
She's mature for her age considering how she takes her future into account by starting her own marketing team and being a manager to Russel Brand (as seen in Big Time Beach Party) and BTR member James. During her scams she enjoys wearing a tree hat as a disguise. She takes every opportunity possible to make a few quick bucks and even though she is independent, she is also ungrateful and naive at times, as shown in Big Time Strike when saying being a mom isn't hard work.
Unlike most girls her age who are shown to obsess over boys appearance and social status Katie doesn't care about any of that. Katie shows a much bigger concern for her family than anything else, and would much rather put all her energy worrying about them. Katie has almost no interest in things that other girls care about which is why she can be somewhat socially-inept.
At times she can be sassy but at the end of the day she is still lovable cute and everyone usually goes to her for help. As seen in Big Time Fans and Big Time Crush anytime she punches James on his stomach he passes out indicating that she might be stronger than him.
She is a good little sister to Kendall and the boys. Her nickname is "Baby Sister" (she calls Kendall "Big Brother") which Kendall frequently calls her especially when they are plotting something. There's a tight bond between the two and they always support one another. Though it is stated in various episodes that she lacks friends she seems to be friends with Tyler a plump redhead. She is clever and wise. It is also suspected that Katie has a medium crush on James but does her best to deny it as seen in Season 2's second episode "Big Time Fans". In Big Time Halloween she and her mom were witches.
At the beginning of the series her mom was worried that she didn't have any friends but she isn't worried or sad because of that. She is really happy and she loves Hollywood because she can earn a lot of money very easily from the people in Palm Woods whether they are kids teens, or adults. In Big Time Audition it is shown that Katie loves to watch FOX and talk like them as well.
She once stated that she wants Dak Zevon to autograph his picture from the magazine to put on her wall (in "Big Time Photo Shoot"). Everybody (especially the boys) didn't believe this because they thought she wasn't into this kind of stuff. But Katie replied "I'm a pre-teen girl. He's a cute pop star. I'm not made out of stone you know." In Big Time Photo Shoot it is shown that she can make anybody do what she wants by doing her puppy dogs eyes and sad smile although this doesn't work on Dak Zevon's security guards because they knew she just wanted to see Dak just like the other fan-girls.
It seems that her dream is to be a celebrity agent or a celebrity manager. It is shown in "Big Time Fans", how she tricked James into signing a contract deal with her which one of the clauses read that she will be his manager (and doesn't like him).
She stated in Big Time Beach Party that she hates the beach but then she finally agreed to go when her mom said that there are a lot of celebrity beach houses so she might get a lot of celebrity autographs. She wanted the autograph on her talent contract claiming her as their new manager. Meeting Russell Brand and working on his party he decides to let little Katie be his manager. Making her wish come true.
She always helps out Kendall and James sometimes Carlos but she has not really helped Logan though this could be because Logan is smart enough to figure out his own plans however she does help Logan with Camille on Big Time Returns.
Katie Knight's signature features are her long brown hair (unlike her mother's curly hair hers is straight) and her Brown eyes, She usually wears hoodies tops jeans and sneakers and rarely wears shorts or dresses. She has bangs as well. Katie is usually seen wearing a watch on her right wrist. In season 1 Katie is normally seen with a purple watch a couple of times white but later on in the series it's either blue or red. The color varies but her red watch was a digital watch. In season 3 and 4 she tended to wear lots of plaid shirts as well.
Katherine Alexa "Katie" Knight is Jennifer's daughter and Kendall's younger sister by 6 years. Katie along with her brother his friends and her mother came from Minnesota. Katie usually hangs out with her brother or his friends. She was originally going to be named Apple but Kendall talked Jennifer out of it.
Relationships With Other Characters
He is Katie's older brother to whom she sights as a role model. The two share a loving relationship for they always get along and refer to each other as "Big Brother" and "Baby Sister." Katie helps Kendall with almost anything. Kendall also talked their mother out about naming Katie "Apple."
Kendall and Katie have never fought. The closest they have come to a fight is in Big Time Pranks where they end up having a draw and sharing the crown after a guys versus girls prank war at the Palm Woods. They also make a good team as seen in Big Time Dance where they both tried to find a suitable date for their mom and ended up getting Fabio to be her date.
It can be noted that Katie doesn't like to say no to Kendall even when his requests may lead to her own discomfort or disadvantage. Such requests can be seen in Big Time Fever where she leaves her snow cone stand in order to help Kendall although she was fully aware that Mr. Bitters might shut it down if she left and also in Big Time Contest where she agrees to hang out with Bobby although she couldn't stand him and ended up punching him.
Katie even helped Kendall in developing his relationship with Jo. Kendall might have remained Jo's stalker if Katie hadn't called out to her and eventually revealed that Jo was only pretending to have a boyfriend. She also encouraged Kendall in "Big Time Girlfriends" when he was contemplating a break up with Jo since they were both getting too busy for each other therefore inspiring Kendall and Jo's one minute date. In "Big Time Break-Up" she helps Kendall figure out a way to persuade Jo to go to New Zealand and take the role of a lifetime. When Kendall is devastated after he makes Jo break up with him she tries her best to cheer him up. She even hires a clown to come to their apartment and make him laugh. In "Big Time Decision" she finds Kendall outside Rocque Records struggling with his decision between Jo & Lucy. But she reminds him that his heart will always find the answer by walking it out and reminds him that he can't run from his problems.
Kendall often relies on her wits and indirectly described her as someone who is devious and someone who can think like Gustavo in "Big Time Crib". Although Katie's plans are always quite clever they don't always work as seen in "Big Time Move" where she advised Kendall to manipulate his friends so that they'd stop fighting.
James is an older brother figure to Katie as seen in "Big Time Crush" where James becomes overprotective of the 11-year-old when she first starts dating. "...She's like a sister to me" he says although in the episode Big Time Fans he thinks Katie has a crush on him although she tries to deny it.
Carlos is also seen as an older brother figure to Katie. Usually when it comes to advice about really anything he goes to her for expertise and whits as seen in "Big Time Prom Kings" when Katie helps him score a date to the Palm Woods prom. They even worked together as "Robin" and "Hoodie" to outwit Mr. Bitters and stop him from overpricing the vending machine's snacks particularly Fruit Smackers as shown in Big Time Sneakers.
Logan is also considered as a brother figure to Katie even though there is not much interaction between these two. Just like the other 3 boys he's there for Katie when she needs him and vice versa.
Katie and Gustavo have similar characteristics for they are both stubborn and bossy. Just like the boys Gustavo goes to Katie for advice/help as seen in "Big Time Love Song" where Katie interviews Gustavo for her school report and she makes comments about his "awful" love song". In the end Katie helps him by taking him for a day out of the studio where he is always stuck. Also in, "Big Time Single" when Katie cures his writer's block when writing BTR's summer single that had to "rule the world" and have the word "beach" in it.
Not many times they are seen together but Kelly can't resist Katie's puppy dog eyes. Kelly seems to get along with Katie unlike Gustavo she even used a sweet voice just to get Katie to tell them her mother's secret Snickerdoodle recipe.
Katie has spied on Jo to see if she really had a (before Kendall) boyfriend. (Big Time Break) Katie also seeks her for help when Kendall and the guys say that girls are not allowed in their prank contest because it might get "dangerous". In Big Time Decision she also supports Kendall picking Jo instead of Lucy.
- Mrs. Knight claimed that she has never dropped Katie when she was a baby. She has a slight tendency of being competitive as shown in Big Time Pranks and Big Time Girl Group where she and her mother's competitiveness made them lose two friends. She also highlights these tendencies when she said "you play to win and not to lose."
- In Big Time Songwriters Kendall revealed that Katie was going to be named "Apple" but he had talked his mom out of it.
- Sometimes when Katie carries out any money-earning schemes she says to her mother that she is going to use the money for college.
- In Big Time Rocker she only appears for a minute when someone in the Palm Woods gets paralyzed. She asks "Why does everyone keep getting paralyzed?" and by that gives Gustavo and Kendall ideas about their rocking song.
- In Big Time Halloween it is shown that Katie knows magic.
- In the original "Big Time Audition" in which Curt is "Kendall" Katie is shown to be older and is not played by Ciara Bravo. After Kendall Schmidt got the part the producer changed the script replaced 16-year-old "Katie" and Mrs. Knight.
- Katie has a habit of pulling at the guys' ears and dragging them aside when she has something important to say wants to show them something or doesn't want to talk to them.
- In Big Time Break Up it was revealed that she reads everyone's contract.
- In Backstage Rush it is revealed Katie is fluent in French.
