PC for

I was gonna add a lot of blood to Sassy, but decided to do something that wouldn't require a filter so I just put a knife behind her back

As for the title, you may not get, will be explained now. Sly (Orange) is supposed to be a tsundere, saying No! While Sassy (Red) is supposed to be a yandere, so she is saying Yes! And Slick (Yellow) is saying IDC (I don't care) because he is supposed to be a kuudere. 

Tsundere: Tsundere is a word combining two words, "Tsun Tsun" and "Dere Dere". Both terms describe attitudes of a person. "Tsun Tsun" is used for cold/blunt/curt attitude, while "Dere Dere" is used when a person becomes spoony in front of his/her lover. 

Yandere: a person (usually female) romantically obsessed with someone to the point of using violent means to get them in their arms. Often seen with a sharp weapon and a psychotic grin.

Kuudere: a character that is cold, blunt, cynical, and pretty much doesn't care if her beloved dies. That's what she is on the outside but she is actually caring and nice on the inside.
