Yes! I will have that up as a prompt. Himeka doesn't do a lot of pre-planning so it's definitely going to be like "oh I had this fun idea you should come with" to everyone assembled.

One thing I also thought of from her encounter with Zenos is that as far as she knows there's no way to prevent someone from hatching from the dreamscape.. (She tried). So the whole dreamscape sequence may be their indication that people are coming no matter what.
