What more were you realistically expecting? Dahlin to claim that it was actually Monica assaulting Nick, Dahlin to claim he's never even met Monica, or to say she's been texting him non-stop for weeks trying to get him to lie?
It basically paints her to be a giant liar. Sure, all of those tears in the deposition were obviously fake, but now there's no doubt, and if she's willing to lie about that, then is there anything else she won't lie about? How can any reasonable person on the jury be expected to trust her at all?
Maybe you were expecting something a bit more substantive, but how many words does it take to say, "None of that actually happened." and "Oh by the way if it did, I would have have noticed." and "Had I noticed I would have done something about it."?
