Aaand I totally forgot to answer your question. So sorry! I swear. My brain forgets to work sometimes.

I don't really mind who goes on the ruins adventure. In play, you have Ferdinand, and I have the healers. If only a couple from the orphanage, then I'm good with bringing some "old friends" in. After an inquiry, they could meet at a rendezvous point, come to the orphanage, or a mix of both, depending on who would be on the way.
