Super late to this whole conversation, but well - Willow, like Lillian, will start up a bit uptight. Or rather, loner. So it's a good thing Calliope ran right into her. x) 

I'm hoping to see how it goes in IC. I intended to have her character evolution go from loner and un-used to socialization all the way to more sure of herself and part of the team, trying her best to belong, etc.
