Since Saturday, November 17th, I found out that Boomerang aired a leaked episode of Ben 10: Omniverse.
Here's the leaked episode: "Many Happy Returns".
Gwen and Kevin return. (And you thought they were gone for good! Boy, have you thought wrong!)
Gwen has a new look. (Does it remind you of Velma Dinkley from Scooby-Doo?)
Kevin and Argit head to Khoros and Kevin makes a deal which includes marrying Looma. (Looks like the Gwevin fans are just as shocked and outraged as the Benlie fans were in Hot Stretch.)
Ben goes Four Arms with a new look.
The next leaked episode is Gone Fishin? which airs Saturday, November 24th.
I quote Bart Allen/Impulse: "Oops, spoilers!"
