There was no intelligent response from Sam, of course. Only a growl as he threw himself towards that wall with a torrent of blood.

The first layer of the wall went down easily. The second (and more) layer behind it was unexpected (in as much as Sam could be said to be expecting anything, in his current state, which wasn't really the case), but he didn't hesitate, trying to plow into the wall through the haze of his own ragespew even as the extra layers bent in to trap him.
