User blog comment:OverlordRocks/What is the plot of season 7? (Let's look at the facts, work together, and have everybody collaborate!)/@comment-25650981-20160325181134/@comment-27507964-20160325185513

It could be the Overlord again but it looks doubtful. We would've seen SOME reference to him in the poster that was leaked, possibly as just red eyes, but we see nothing. I don't think he will return in this season, and I think it would make a great story if he returned in the Final season, which this may or may not be.
