They are skipping pretty much -_-

They should have at least explained why Ashley gave in helping Grayson to become a firefighter. Or at least clearly draw it, since it is actually pretty important later.
Grayson inherited a trait from his DO father Koi, Koi moved his ears when he was exited.
And Grayson uncontiously does that sometimes too. He did that when he was talking to his father Ashley.

Also the phone calls Koi did, one was to Chase. And that is interesting for KMIYC readers, because in KMIYC they had no contact.
