Mechanics questions

[zort]

I can now mostly answer the first question, and I've written my full answer here. To summarize, the grabbed guy can take any number of punches from the person doing the grabbing, but can only take four punches from other people (which is the same as the number of punches he could take if he were standing up, only here he doesn't go into DoP first), except sometimes when he can only take two punches.
