In regards to my characters the ones she is probably most likely meet out and about are Cameron, Elijah, Gabe, Rhys, Roman, Seth and Michael. They're definitely my more outgoing social and tend to frequent bars, clubs and other such fun places that they might run into Hollis.
And if she's got money to burn then Tooth and Nail is a good place to do it.
Amused by the thought of Hollis and Nikolai hunting the same prey.
Potentially the Magisterium may have made use of her skills which means she might have encountered Daniel annnnd local law enforcement by the way of Wyatt!
All others not mentioned are totally up for all the random :)
