A little late to the Episode 10 party, but I finally had a chance to check it out. In bed, with the lights out even!
Spoiler for Just in case:
When Izumi was tripping down the embankment in the beginning of the episode I was going "No. No. No no no nononoNONONONO!" and then a huge sigh of relief that she was OK.
I'm a little angry with Mei. If she knew who the extra student was, she should have said something. Perhaps next episode will explain why.
I knew she was going to be interrupted, but I still jumped when the door started banging.
Damn cliffhangers!
