[ Rick doesn't move. He doesn't fight or protest when Tetsuo pulls back just slightly -- has his moment of fighting and doubting. Rick doesn't move away. And only after Tetsuo speaks does he reach out to ruffle the kid's hair with fond affection. ]

I don't doubt you, Tetsuo. So you shouldn't doubt yourself.

[ And finally he pulls back just so he could look at him fully, focus in on him. ]

I failed you. I failed you an' that's on me. You saved my life that time, an' I couldn't even...

[ His brows furrow. He knows this is probably the last thing Tetsuo needs to be saddled with right now, but how could Rick sit here and be happy about Tetsuo coming back when he couldn't get over his guilt? ]

I lose people. All the time back home. It's never easy to accept it. I jus' never have to face them, to tell 'em that I failed.
