Something to consider for your next session one:
After character creation, before back stories and whatnot have been all set in stone, go around the table and have each player say how they know one other character there. Then, on a second pass, have each player add a secret to another character, something that only that character (and maybe the person who’s coming up with it) knows.
It takes some trust and a bit of not being a jerk to pull it off, and of course, the player can veto if they really dislike what’s happening to their character, but it can lead to some really interesting inter-party relationships.
Behind the screen, you are creating a
map with arrows and lines connecting your PCs, so you can see at a
glance who knows what about each other and how they’re related.
Talk to your players about it and maybe give it a shot!
