So I just saw the Season 2 finale of Kid vs Kat and, well, it was actually really awesome, but the ending with Millie, Lorn, Harley and Fiona's memories (about Kat being an alien) being wiped, kinda sucked, especially considering that it never got a Season 3... I think it could've taken a really interesting turn with them finding out, like maybe Coop's team would have more force on it with Lorn and Harley joining them, and the new agent that Kat Commander sent on Earth perhaps competing with Mr. Kat to try to outdo him and bring the invasion sooner, and while Millie would know Mr. Kat is an alien she would still be oblivious to him being evil.

Just an idea though; an idea that sadly won't happen, considering that the show ended 6 years ago...
