Woke up going FINALLY a coherent dream that's actually nice
In presumably the pesterquest timeline, the beta kids are all hanging out in Dave's apartment, the most dangerous possible shit to be doing
Dave gets antsy that this is the most dangerous possible shit to be doing and they go out on some adventurous walk together.
Eventually they meet some extremely grizzled dad type who is on the run from the government (the government is in the wrong on this one as per usual, my brain assures me),
who had lost his kid at some point
They take Dave under their wing and Dave gets a nice guardian :)!
