Ok, I love this show and this episode was good, but was it really necessary? It seems like such a throw away thing to happen, I mean, if they'd all stayed calm most of the people who died there wouldn't have died (such as the girl who fell out the window trying to kill Mei).
I also can't for the life of me work out how Takako died as sure she got her head stuck in the cables, but why didn't she just you know... step back?
EDIT: Also, last episode Mei said that she knew the other was here meaning that she knew who it was. Why didn't she just bloody tell anyone? :/
