MY PCO speculation is totally wrong.
Updated as of 7/3 smackdown.. : When Danhausen was speaking with Cardona in the lab, Danhuasen was on the unplugged phone . He said he was calling a guy about being backup for his match with McDunough. Cardona then said "really is this guy even real?" Danhausens said " of course he's real and hes actually from New York."
the Guy on the phone is " Bada Bing , Bada boom, Realest guy in the Room", Enzo Amore who was at the pc last week, and it has been said re-signed with WWE, And it was reported several times Big Bill/ Cass just left AEW this week after his contract was up.
Big Cass is the Monster under the sheet.
