Brady's Wound

You gotta hand it to Brady, he must have balls of steel.  It's clear from how his shirt is stained that the bullet didn't just grave the side of his arm or something, it hit smack dab in the middle of his shoulder; and there's only a fleck of blood on the backside of his shirt, so clearly the bullet didn't even go all the way through.  So not only is he just casually walking around with a bullet in his shoulder like it's no big deal, earlier in Tuesday's episode he's even banging that very shoulder against the door to try and force it open (never mind that the door opens in...).
Plus, come to think of it, I don't think he can even take anything for the pain, on account of being a recovering drug addict.
