Of mine, the most obvious connection is Lorelei, who would know Drew through Foster/GWTF. She's been dating Foster for just under a year now, and I can kinda see her treating Drew (fondly) like a younger brother? Regardless, The Dreamery is always open to him and Foster both if they need an AC break or to go stand in the walk in freezer for a bit. ;)
Duncan's sister is Drew's sister's friend? lmao. Not much of a connection, but probably at least an awareness.
My only other Aurelius (besides Duncan) is Xing, who was a little closer in age, but not much. My folks are all old, sorry.
