Fortunately, it clicks pretty quickly that this is not something John needs to have in his hands. He drops the bomb back onto the chair and moves to try and push Jade out of the way while simultaneously moving back himself.

"Jade, move! She rigged i--"

The bomb goes of, sending tiny shards of metal and glass and god only knows what else everywhere. Of course it couldn't just be a regular bomb. Of course. And while John at least made an attempt to get away from it, he was more concerned with Jade then himself and ended up taking the brunt of the shrapnel to his face and chest.

It hurts so bad that he can't even attempt to vocalize the pain. All he can do is stand there, bent slightly double with a wide-eyed expression of shock and horror plastered on his face. For a good thirty seconds or so, he's doesn't even breathe, though eventually that comes to a very ragged, shallow end.
