... why would they gossip about the WORST EVENT they've suffered so far, since transferring to the New World?

Isn't that usually what people gossip about? Things that are bad and annoying them? People who did stupid or mean things to you? I mean, as far as the mimics are concerned, the whole thing was essnetially Kath's fault, even if it was unintentional, so it seems natural that blame should fall on her from their point of view. Of course, Graft is also to blame - in their eyes - but that much was obvious.

Something along the lines of:

Toaster Mimic: "Can you believe what that witch did?"
Mailbox Mimic: "I know right! She ruined errything!"
Toaster Mimic: "Bringing [i]that man[/i] into the Queen's domain! And revealing the Heirs!"
Phonebooth Mimic: "Darn-low despicable it is! Coming here and insulting the Queen for borrowing her books, then stabbing us in the back!"
Mailbox Mimic: "Dragstabber!"
Toaster & Phonebooth Mimic: "Dragstabber!"

Something like that?
