So I guess the big question is....was Fury screwing with the AVENGERS that he was dead...or is he LMD?
I think that would be way too confusing.Considering that they're gonna be inspecting supernatural elements and that Ghost Rider is back in-house, it'd be cool if Mephisto was involved in Coulson's return. Though I'll admit they'd have to get really clever to have it make sense story-wise, rather than do it for the sole purpose of introducing that world.
My personal belief *stands on opinion box - not that I need to - but it's Monday and my brain is in a weird place - and naturally, some of this may depend on exactly how he's brought back* for a long time has been that I am perfectly fine with Coulson coming back from the dead SO LONG AS there are ramifications to it. If everyone (read: The Avengers) were just hunky dory with it and everything was sunshine and roses between them and SHIELD, then yes... I agree that it would most certainly cheapen his death. However, I personally don't see that happening.
What's more important is that Fury Lies, not that Coulson Lives
