Wilt

[Verity]

I'm having this silly vision of Wilt playing basketball with his creator. The kid shoots and misses Wilt, who flings himself after the ball. Unfortunately it ends up in the street as a lorry is passing, and his arm ends up under the tyres.
Later a doctor tells him they have to amputate it.

I know it doesn't make sense, and I don't believe that's what happened At least it's not too disturbing.

If they let us know what happened to him, I don't believe it involves lots of blood and violence, considering many viewers are children (teenagers and grown-ups would most likely be disturbed too). If we never get to know, I'm still sure the creators don't have extremely macabre ideas about it. Sad, probably, and maybe involving some violence, but as I said... you know.
