Jimmy was unbearable in the season premiere
From the start when he found out about Chuck it was so boring and unbearable watching him go around all silent and moody for the next hour barely uttering a word. Not giving a fuck about his brothers obituary, right up until the end when he gladly let Howard think he was cause of Chuck's death then went around whistling and making coffee like he was in a great mood.
I was like so wait Jimmy doesn't give a fuck about Chuck dying? Then why was he all moody and silent the entire episode then?
