Kevin, Kenny, and Karen are all siblings in the McCormick family. Kenny and Karen are relatively close, while Kevin isn't as close to the two.

Kevin is sort of harsh, and slurs his words because he is drunk most of the time.

Kenny is pretty sweet, yet flirty. His words are always muffled because of the thick parka he wears, usually making audible "mmph" noises. He can still speak normally.

Karen is shy, and mostly hides behind Kenny when she is scared or nervous.
