User blog comment:OVERPOWERED99/Toothless being responsible for Hiccup's leg?/@comment-3230751-20150103225723

I would say it is possible that Toothless bit off Hiccup's leg, but I wouldn't say the quote from the second movie particularly solidifies or proves it. I think there are many possibilities, just as there are different options on what could have physicially happened to Toothless's tail (did the ropes sheer it off, or did smashing into trees on the ground rip it loose?). I don't think we have solid proof on what happened to Hiccup's leg, but I'd be open to the Toothless biting theory.
