the argument was aggressive

The knife was embedded in the wall. Nothing could give it reason to release it's grasp. And the hand it had pinned there involuntarily slit it's fingers on the blade as it tried hard to free itself. But the wall would not let go. No digression, no recession.
The argument had simmered until the one with a painfuly unusable hand at the moment had whipped things into more dangerous territory by waving his .44 caliber friend and threatening to let him do some yelling, seeing as his own voice was "getting hoarse." The other participant was not distrubed by this new addition to the conversation and instead introduced his friend, the one with quick-cutting, sharp wit.
And in a few short seconds he had his opponent pinned to a wall of his logic.
