Jack is not, generally speaking, an outgoing guy. He doesn't have a tendency to greet new faces to Thorne — largely because he doesn't even notice them. It's entirely possible there are people that have been in this faction with him for years that he would not recognize if somebody held a gun to his head.

Evidently, the universe seeks to balance out his introversion in the form of his familiar, who has taken to making friends on his behalf. In this case, it's in the form of a rather chonky raccoon who may or may not be slightly glowing a neon green, and who definitely has a set of luna moth wings fluttering at her back.

Said raccoon has decided to play divine intervention, and quite rudely invites herself to climb up Evelyn's back to perch on her shoulder. It is not graceful. She is heavy, as rotund as an overweight cat, but she is Very Invested in whatever it is Evelyn is reading. Her little bandit paws reach out, fingers gripping, encouraging her to turn the page.
