After last game with Blue as host no idea
Usually it just flips targets, so he bus drives Mwil and Heim. Any move put on Mwil will be done on Heim instead. So if someone killed Mwil as a move it kills Heim.
Blue had it that Mwil tries to kill Touch and Heim protects Pickle. the only thing that happens is Mwil Kills Pickle and Heim protects touch
The fact that Racks never explained it is very frustrating, though im not sure anyone asked lol
Not sure how a host would treat that. Do you target them, visit each, a remote visit type. So many possibilities
