Guys, I just have a half horrible/half funny idea about what it can happen in this episode; and in the whole arc. Do you remember the episode "Simian Says"? At the end of the episode, after saving Spidermonkey's planet from the DNAliens, Simian sold some DNA Repair Guns (the ones used by Ben's team to turn infected DNAliens back to humans) to Emperor Milleous of the Incursians. Well, I suspect now we are going to see the solution of that cliffhanger.
I suspect, what if the Incursians managed to modify the DNA Repair Guns for their own purposes? What if they created a version of the gun that can actually turn any sentient being... into an Incursian?!!! I mean, what's the best way to conquer the enemy than to turn them into your kind? And I have the uspiction that Vilgax, possibly in a moment of weakness after his defeat against Ben with Ascalon, will be victim of those guns and turned into an Incursian.
What do you think of this idea?
