Spoiler for Episode 6 of Toradora!:
The first 2 mins before the OP is definitely the best scenes ever.
Taiga surely gets her hand on Ami on this episode.Not enough with the raep scenes with Minorin on the class,she even tortured Ami inside her house,although the last scene before the ED hit her directly on the head (is that a sign of jealousy?).
Even Inko chan's reaction to that gives the sign as if a "massive storm" will hit Ryuuji in the next episode.
Well at least Ami in yandere mode is not bad too.
So the real reason why she disguise herself in the previous episode was because of a stalker that keep stalking her even after she changed her school.But after seeing Taiga chasing the stalker away without any feeling of fear and scared,she overcome her fear and chase the stalker away.
Next week episode - POOL EPISODE!!!Taiga on swimming suit ( ^3^)
