Anything that comes out of Fluffykin’s mouth is purely said with her own agenda in mind.
Exactly correct.
What do you think her hidden agenda is? Or is there a psychological factor?
Her agenda isn't hidden. She only does things that will further her own interests.
And her psychological factor? She's nuts. She claims to be a psychic but has counseled Heather to make incredibly bad choices. Maybe that's why she's "listener" Lasha now.
Lasha was the push forcing Keith to replace Heather. Lasha implied that Keith was cooking the books to Heather's disadvantage. Lasha was the first point of contact in getting Heather on Vara's network. Everything Lasha has done was bad for Heather.
Edit: I wasn't implying Lasha was pushing Keith to dump Heather rather Lasha was encouraging Heather that MitD needed her and she was indispensable.
