Sure, was just wondering since the last time we looked at this he was thinking he may have let Raynor down and his healings were not going so well.
Yes, that's true. I see it more like he knows that he's trying his best to do the right thing. Unfortunately, things didn't go the way he'd like them to go. And now he's a bit scared that Raynor is going to be unhappy with him.
But that doesn't mean he has lost faith.
