Original Commentary

Yes, Robert has interacted with Silver_Blossom before. He introduced them. Isabel pointed this out to me and I may explain it in future comics. But the short version is that while she's been in a group with Robert, they haven't actually talked much. She actually knows Brisbane, while Robert has her filed as "ok person to game with", and vice versa - Terrence

Modern Commentary
In FBAO, at this point, level 55 is pretty high and getting that last 4% will take an hour or so of grinding.

Also, Joy knows about the Solar Globe too. She's probably on all the same FBAO messageboards that Jake is. - Terrence
