I think Hoshino recognized that all the getting stabbed, and as she'll eventually find out, the two of them running away together was the result. She suffered enough already, and Sana picked up on that.

When she told him about how she felt running to save Shuri, he responded rather forcefully and quickly. I wonder if the scar or whatever hidden under his wristwatch has anything to do with the way he responded.

Back to Hoshino, she'd been lying to everyone this whole time. The part in the speech where she said she always imagined doing terrible things to teachers and classmates. That certainly never fit with the impression we got from her before, but I thought it was very convincing. I wonder if she'll really give up on the sweet side and become nasty all the time, she certainly did a good job on Shuri when she told her the truth. Or maybe not, she's been lying about her personality for so long, she probably can't break the habit.

I love when Mai Nakahara plays evil characters, especially the ones who start out so sweet sounding. Ryuugu Rena <3
