That's what I thought when he was talking to Kaori. He was saying their method of pretending to be her enemy so they "did have to see her smile" was BS and inconsiderate, right? He suggested that they should have spent time with her, and make her realise that even if her memory's erased, she'll have better, warmer ones the year after anway, right?

Then in the preview Touma says "I'll get you out of there", which boggled me.
