On the contrary! First, not a killjoy. Getting some perspective on the fact that MitD is a secondary character is crucial to properly gauging clues and their relationship to the story.
Second, this is not in fact a guessing thread. It's an analysis thread. The guessing is so secondary to its function I never even considered keeping records of who said what, and only because Crusher stepped up does this thread even keep such records.
So please do not feel bad at all.
As to the reveal, I suspect we won't even get an explanation for the escape. At best, I think MitD's species might get a shout-out (although maybe only in the strip title), and he will let those that care do the footwork. He's just not important enough to warrant even a panel or two of explaining what he can do, because the story doesn't do that for anyone. Big blue guy can open his mouth and spew lightning? Unexplained. That's just what big blue guy does. Story has already established anyone can have weird powers. And MitD already has demonstrated teleportation, so there is no need to tell us he can, much less how.
