Thanks for updating!
My dad thinks The Alien could be Rashida Jones.
Raven as The Raven was too obvious. I pretty much figured out it was Ricki Lake when she talked about a loss/death (I knew her husband or an ex-husband had died) and I caught a couple of references to "Hairspray". And The Emmy was definitely a big giveaway because I don't think Raven has any Emmy's, except for maybe, "That's So Raven".
The clues The Peacock shared last night were total indicators that it's Donny: the rainbow color of the cape he was twirling around in the video package; the wig and "being thrown in jail" were all obvious references to Donny playing Joseph in "Joseph & the Amazing Technicolor Dreamcoat".
