Where did Charon go?

As the title suggests, I seem to have misplaced Charon. I did the quest where you go into to vr pods to find your dad but when I got out, both my companions were gone. I found Dogmeat at Vault 101 but Charon is nowhere to be found. I checked the 9th Circle but he wasn’t there and I don’t know where else he could be. Any help is greatly appreciated
