Sometimes I wonder if our favorite historical figures look at us from the afterlife and say “that’s my person. That’s my person and I will guide them thru the next seventy-five years” and then there’s others that are more “you read my wife and I’s letters one more time and I will end you.”
So I had this silly idea of Rowan returning to New York to exact revenge on the Ghostbusters…except that he’d be reduced to a much smaller and weaker form. Patty basically adopts him by begging the girls to not put him in captivity like with the other ghosts. Shenanigans ensue from there! He wouldn’t even be a teammate or a pet….just mostly a test subject for Holtzmann’s experiments haha.
