What so we could see Yamato at Suzuka's throat for no reason other than I like you and don't want you to go out with other guys. It'd be repeating from when she was still hooked on her dead boyfriend. At least now there is a chance that they could develop a better friendship than what they had before when Suzuka was at his throat for being irresponsible, lazy, etc... Now she is nice to him and isn't as critical of every move. Yamato just needs to look past his affection and not act like a retard around her.
No way at least that would have been believiable.
