It could be just really really really good acting at the end that he managed to scare everyone out of their wits.

These are the worst candidates to hope for such a thing.
Drift wood part was super cute, it completely characterizes Ren's situation, for quite a while now Kyoko has been his driftwood.
Next chapter I see Kyoko trying to resolve the situation with her Setsu "coolness" and how she will decide to act to help Ren resolve his battle, use her Setsu charm/creepily close sister charm, or express her concern as Kyoko (doubt that will happen as she constantly thinks she'll become a worse actor if she leaves character at any moment)
