Alyson has pride to spare, so I think she will get along great with her new HoH. Nicole....she couldn't tell you who the previous HoH or mentors were, so she will be Meh.
Kristen isn't in his class so probably won't have much interaction. Delphine is oblivious, he is a male so she won't really trust him.
Chloe will be professional and perhaps even friendly. She hasn't exactly warmed herself to the rest of the staff, so who knows.
