OP - I kind of imagined that they wake up connected across universes. Still doing their thing in their own universes, just with a bit of extra commentary going on.

I wouldn't be against some universe crossing though because thats like... another fave trope I have.

God Matt is so so likely to get snippy with probably all of his alternate selves. (My kingdom for him being 'oh god no that's horrible decision making skill why' at one of the alternates because i feel like if Matt was the viewer of his actions rather than the partaker of said actions he'd be very against everything)
