As to the kid, the new guy did it, and it shocked Walt and Jesse IIRC.

Little is shocking to Walt anymore and he's developed a blind spot to just how evil he is becoming. Jesse has long figured out he wasn't capable of being a big league criminal, but he just doesn't know what to do with himself otherwise as he goes on mostly passively with the increasingly dark flow of events.

Jesse has long figured out he wasn't capable of being a big league criminal, but he just doesn't know what to do with himself otherwise as he goes on mostly passively with the increasingly dark flow of events.

I think he has certainly struggled with the violent aspect of their business but he was the one who came up with the "big idea" in this episode. I think, like Walt, he has gotten inured to the violence. That is why the repercussions of this latest death should be compelling.
