[Dick lets out a slow sigh because let's face it, even outside of this incident, he knows how shitty it is to find out someone you thought you could trust as a friend and coworker was actually more or less stabbing you in the back.]

I'm sorry. I don't know who else she told, I don't know why she told me, and if I'd known you didn't know, I would have said something earlier.

Why the hell wouldn't she have told you?
