Been on my mind..

I’ve had to questions that’s been pondering my mind for a while and is now resurfacing. Is the severed hand in Season 1 Callippe’s hand? Cause in Season 3 you can see the same tattoo on Callippe’s hand?

Also, In escape the night season 3 who did Colleen (aka the disco dancer) vote for to go in the “maiden of madness” (Season 3 Episode 6)??
