She knows her husband
>sucks.

granted probably Cam was the first to cheat before they had kids.. but Daphne didn't do herself any favors by sealing the fact Cam will see "my wife cheated" when he looks at their kid...like, forever rubbed in his face. and i'm sure that propels him to cheat even more at every given opportunity.... the scene of him angrily flossing not wanting to be part of the video call was so quick, but crucial for explaining why he "sucks" i think.

(and i think it's noteworthy he's conscious enough to use a condom in contrast)
