It would make more sense for them to come together as a temporary separate group, I agree- but I dunno about everyone dogpiling on that wolf quest. It could turn into a mess with so many people, not to mention their quest is already halfway done. Here is what I got as options so far.
-Form a party and go on wolf quest, bump into other group.
-Form a party and go on <insert> quest.
-Lay around town and hussle the newbies for stuff.
-Form a party and go exp grinding.
-Start Barfight.

Miss anything?
