Fortune as the man he was questioning only said the word 'Suffer' to him in return... through the fact that he might have been choking to death may have been a factor in that. Removing his foot from the man's throat, Fortune strode over to retrieve his sword while the fallen knight at least made the attempt at reclaiming his breath... 

Before someone shouted 'Grenade' and the world was filled with an almighty roar that rattled the brain. 

Caught off guard by just how big the shockwave was Fortune found himself on the ground, flat on his belly as he was knocked off of his feet while he was bending down to reclaim his sword. The ringing in his ears seemed to be echoing off of his helmet, Fortune reaching up to hold his head still to try and get his sense of balance back. There was some yelling, but he wasn't exactly in a proper condition to pay attention to what exactly was being said. 

It also seemed to be getting warmer, but that was a trivial concern.
