Friendship History


K.C. and Bianca first met on the off chance when K.C. was trying to frame his mother with a bottle of alcohol. Instead of framing Lisa, K.C. and Bianca get drunk together. The two do not interact again until Bianca began dating K.C.'s friend, Drew Torres, and Bianca was even there to witness the birth of K.C. and Jenna's child, Tyson. K.C. and Bianca remain friends until Bianca gets mixed up with Vince Bell's gang, and K.C. chooses to stay away from her. However, in season 12, the two grow close again when they are both on the academic quiz team. They stay close until the time K.C. and his mother move away to British Columbia.

Season 10

Normal 1008
In Better Off Alone (1), Bianca is at The Dot when K.C. and Jenna come in. She sees the liquor bottle K.C. wanted to use to frame his mother fall out of his backpack, and she asks him if he has plans for that bottle. When he says no, Bianca offers to make some, smiling at K.C.

In Better Off Alone (2), the episode starts out with K.C., Bianca, and Fitz in a car drunk and hungover. Jenna then approaches and talks to K.C. about his mom. He gets up, ready to get back to his complicated life.

In The Way We Get By (1), after Drew is turned down by a girl, Bianca playfully teases him about. K.C. explains to Drew that he's "gross by association" for hooking up with Bianca in the boiler room. Later, when Drew is playing the drums in a room, she enters and starts dancing along. After Drew tells her she ruined everything she tells him then what happened at Vegas Night takes two people, and they continue to argue, until Drew realizes Bianca likes him. She tells him " We had a lot of fun together. We could have a lot more." The two begin to make out. Later, they are walking down the hall together, with Drew's arm around Bianca. He tells her she should come to the basketball game. She responds by saying "A bunch of jocks chasing a ball. Sounds like fun." When Drew says that he wants to bring Bianca to their date night, K.C. seems uncomfortable by the thought and tells Drew he can do much better. He also doesn't seem pleased by the idea of Bianca showing up to the big game, and tells Drew not to lose his focus. But at the basketball game she shows up. During the game, Bianca smiles and waves at Drew which distracts him, causing him to be hit in the head with a ball. After that, they win the game. Bianca, Sadie, and Jenna run up to Drew, Dave, and K.C. to congratulate them. Bianca asks " Where are we taking this party?" Drew says their going to Little Miss Steaks, but Jenna rudely responds by asking, "She's coming?" Bianca stops smiling, looking hurt. Drew says, "I can tell when we're not wanted. " And they both leave.

In Drop the World (2), Bianca is seen at K.C.'s bachelor party with Drew. She says this party is lame and goes to find something to do. She comes back with Twister. So K.C. handcuffs himself to Bianca. She thought it was funny until Dave didn't have the keys. They then try to break themselves up. Later, Chantay calls the hospital saying Jenna's water broke. When they all get there, Bianca later compliments the couple, saying they look cute together with the baby.

When K.C.'s mother interrupts, Bianca tells her that K.C. runs a tight ship for practices, and when she asks Bianca if she is seeing anyone, K.C. looks at his mother and Bianca in embarrassment. Later, in class, K.C. and Bianca talk about before quiz team, and K.C. thinks that maybe they should hook his mother up with their quiz team coach. Bianca asks the teacher if he is single for K.C.

In Waterfalls (2), K.C. and Bianca continue to scheme a plan on how to get K.C.'s mother on date with their quiz coach, though K.C. says he can't hook them up because he promised to stay out of it. Later, at the restaurant after winning their competition, K.C. and Bianca sit next to one another, and they notice his mother sitting with their coach. Bianca teases him about their coach being his new father if they get married.

In Rusty Cage (1), before practice, K.C. tells Bianca and Connor that his father is out of jail and that he can't leave his mother behind with his deadbeat father, though Bianca tells him not to sweat it since he only has a year of high school left. The next day, Bianca asks K.C. how dinner went with his father, and he tells her that Kevin Guthrie, his father, wants to get a job. Bianca asks if he really is going to believe him, and K.C. says he has to give him a chance at forgiveness if he makes his mother happy. During practice, K.C. gets a text from his mother, and Bianca asks him if everything alright, though K.C. reassures her that is probably is, as he puts his phone away.

In Rusty Cage (2), she is seen practicing with the other Bright Sparks, but talks to K.C. about his parents drinking. She knows he's upset and understands that he doesn't want Lisa to relapse. When he answers a question wrong, she watches him leave. Before he leaves the area for good, she is one of the people that come to the front of the school to say goodbye.
