I love how Vergil segways me into an even MORE complicated question/ Gm Ruling<br/><br/>Soooooo<br/><br/>I don't know if Trigon is ever going to get involved involved, I mean I guess we have a Raven now so I can see him becoming an actual plot or mission. However I also know very little about his whole deal in the mainstay comics. I guess if I was going to GO with something (funny how I have Constantine and never thought about this) I would say a version of Hell exists in this "Our Universe" part of the Multiverse. That being said I  always enjoyed Trigon as more of an inter dimensional baddie so I would probably go with something like that. Trigon is trying to break into this reality and wants to use Raven as a portal to do that.
