Ignoring the creepy context-is-for-the-weak aspect of this, didn't I just see this exact same plot with Hawk and Mock on the other side of the fence?
Returning to the actual events of the comic... what I like about Babs/Dinah is that when Babs does some stupid unilateral shit like this, Dinah calls her ass out. When Ollie does some stupid unilateral shit like this, Dinah marries him. It just seems like a much less healthy relationship, y'know?
