Hahahaha!!! They wanted him to help out, they should have been careful what they wished for. I gotta hand it to him--some people pretend they're all about cutting through the BS but really they're just mean. But he's uncompromising with his own stuff too--he was confronted with new info about his dad, he processed it, he asked straightaway, he evaluated unflinching and bam! Out of there.
Unlike his dad who affects the abrasive style but under it he's just a hypocrite wimp who edits reality to avoid guilt.
