Hiccup meanwhile just picks up the leg, gives it a good shake, then reattaches it. Apparently it doesn't bother him at all.

"An alternate what? Okay that's just... CRAZY."

With his leg back, Hiccup then pushes himself up to stand again. Pointing casually at Radley as if trying to make a point.

"Because that's not possible, and I was falling before I woke up here. Sounds pretty afterlifey to me. You sure we're not dead?"

The Gible just blinks at the both of them, clearly puzzled by all of this.
