The going getting tough is not an excuse to be an ### to those around you, especially those helping you. Clark's a belligerent child in an out of control temper tantrum - he's not just being a jerk to Diana, he's a danger to himself and others.
How does this make any sense? Ok, even if I buy Diana putting up with Clark's rude behavior to her as her being a very patient girlfriend, 'hey, let's attack those transporting Parasite so when can attack him while he's chained up' is just Diana being a good teammate? Clark's the one that needs to have some sense smacked into him.
I was thinking S is for stupid, but selfish works well, too.
I'm guessing the plan is to try for A) "make things right," but given the lack of quality on this part of the shallow spectacle of a story, I seriously doubt they can do a good job of actually making things right. It'll be some generic apology, Diana will forgive, and sweep it under the rug. The idea of some bumps in the relationship road isn't bad, but the execution is just so poor I have no hope for it.
This title should be so much better.
