About two months ago, I was able to communicate with my former headmates! They've spent the last 20ish months floating about the earth and surrounding space and I successfully located and contacted them. Part of the reason I decided to return to OKP is that I've asked them to come back into the body with me. I'm not sure if they will, as Iago has found another being he's interested in attaching to, but I hope they do.
It wasn't two months after they left that I began to miss them terribly. I've wanted to talk to them and invite them back ever since.
I'm in the process of discussing this possibility with my significant other, as well, but the reaction there seems to be supportive, if mildly confused.
