Well, I think the "not my problem anymore" vibe is coming from Jared, so you can hope that the tone will be different onscreen.
I also find that reaction so bizarre that it makes me either hypothesize plot reveal that all is not what it seems down the line or makes me think that Sam is seriously crazy in his extreme sanity. That much capacity for emotional disengagement and compartmentalization becomes Sam's version of depression.
