Initial D 4th Stage ep. 2

Can anyone please explain to me what Keisuke's frowning was all about after saying or thinking, "Take a good look at the Ace's skills", "Fujiwara!"( at around 18:00 of ep. 2) [img]i/expressions/face-icon-small-frown.gif[/img] ? Because he suddenly made a face. What was that all about? Why'd he make that face? Was he mad at Takumi about something?[img]i/expressions/face-icon-small-confused.gif[/img]

just an evil look, keisuke sees takumi as his rival so he doesn't really hate him but doesn't really like him either he wants to be a better racer then takumi so for some reason he just gave him the evil(jealous) stare
