I don't think his deal with Gideon is significant. It was probably something that involved getting rid of evidence of the secrets of Gravity Falls. I now wonder, did Bill need Dipper's 'permission' before he could possess him? Bill is obviously not bound by his own deals, but I wonder about the other technicalities.
