Once again, this comic has colored me retarded. I'm going to go out on a very shaky limb and say this flash was actually too obvious and answered too many questions. That's right I went there.
Are you suggesting an as of unreached level of maximum trolling? And that we'll get another flash tomorrow that says everything in this flash is a lie and it was all a joke while he plays the real flash?
Honestly, more than anything I'm worried that Hussie is wrapping up as many loose ends as he can, and racing to the conclusion. I mean, this flash answered essentially every question except "What the heck is the Green Sun?" and "What's next?" Okay, and how and why Grandpa Harley is walking around somewhere. But other than that, I can't think of any hanging considerations left besides how the story ends, which largely encompasses those questions.
Except...He only has one arm, remember?
Despite how large those rings are he does have more fingers. And if he hops to more universes he'll eventually find one that has a kernel that has multiple arms.
And suddenly, invading the Troll universe makes a lot of sense. He's looking for another ring. A ring that will basically make him a God, which he may already know. And, y'know, give him quite a few more arms.
