[He starts to smirk when she agrees with him, but he notices her tense and call the sword back. With how she's positioned herself, he only has time to side out of the way of a very crippling injury--
Only to end up pinned to the wall by the sword, now embedded in his arm. He howls in pain, shell cracked messily, red coating both the wall and the Monarch's blade as he fights not to collapse straight to the ground.
Jack's body shakes as he tries to keep himself still, from aggravating the injury too much, forced to brace himself against the wall thanks to the fact that the weapon has him pinned to it. He's suffering, its great, he looks like he might cry.
And then abruptly, he goes very quiet and looks at PM almost sheepishly, like a young, affectionate puppy at the door waiting for its treat. Suddenly, its like he isn't bleeding all over the place. He looks from his arm, back to PM, almost stock still, not in shock or surprise, but another emotion entirely. He's not smiling yet, any sort of cockiness has mostly vanished, but he appears almost embarrassed.
Public Displays of Aggression, PM, its flattering, but rude. With the fact that she had to get so close to him to stab him properly in the first place, she might notice that his pulse has sped up, no doubt adrenaline from the stab wound inflicted upon him.
He waits for her to either follow through or to drop the sword. If she pulls away to try and stab him to end it, he's prepared, even if he's stuck staring at her in an oddly perplexed manner.]
