The three cats in this picture are Wave, Flame, and Roscoe. Wave is Flame's older brother and he kil.led Roscoe's wife. Roscoe, in revenge, nearly kil.led Wave. Wave is smirking because before he was nearly kil.led he hurt Flame a lot and Flame was too scared to do anything about it. Roscoe still feels a lot of anger about his wife's death and since he believes that Wave is dead, he has no one to direct the anger to but Flame. So...yeah c:
