I have to say I felt sorry for Angel for the whole duration of this episode. She really seemed alone. It actually looks like she was always alone, pitted against the rebels and maybe - it wouldn't surprise me - even against the other council members, because the new president looks more evil than anybody in the series so far. Although I don't really know how this new dude could fare any better against the rebels.
I was completely expecting Otonashi to take the curry to Angel. He's certainly different from the others in the rebels by showing concern for Angel and the whole situation in general. In short, he hasn't accepted Yurippe's world view despite belonging to the rebel group.
