Ahahahaha, I can't sneak anything past you XD Yes, there's a big sea change in this update in how they relate to one another and in how they react to each others' points of view, in that they're really working in tandem so much more now, debating instead of arguing. Even when they disagree, they accept each other and their viewpoints enough to give them fair consideration. Especially for Erik, this is a huge step.

(And yes, the jealousy over Kurt is totally a throwback - or forward - to the kitten thoughts.)

As to your last paragraph... no comment :D
