Because...I don't think it'll work out the way we want.

Reika didn't target Luz, they just happened to be out at the same time. Edward didn't target Thomasin, they were just out of their rooms at the same time. Yuta-he didn't target anyone-he saw Valmont standing outside my door with a knife and moved before he could.

If we go with a buddy system right now...I can't be certain we're not just providing someone a victim.
