If Lydia were feeling charitable (which she wasn't), she could have admitted to the part she played in this immediate shift towards yet another argument with her ex. She could have chosen to leave it alone and not bring it up, that would have been her usual move. Ignoring the giant, closet kissing elephant in the room? Under normal circumstances, she would have sooner jumped into a trash compactor before admitting to even thinking about it afterward. But she knew Matt too well. If she didn't bring it up, he would, and with even less tact than she had.
At least, that was the reason she would tell herself. Her hasty attempt at self-preservation certainly had nothing to do with the fact that she wasn't sure she could actually withstand it if she gave Matt half the chance to use what happened between them as ammo against her now. For most of their relationship Lydia had permanently existed between the combating urges to kiss him and yell at him, and after everything, very little seemed to have changed. She didn't trust herself around him.
While they had barely gotten past that first unpleasant conversation hump, Matt was already plowing full steam ahead and doing something else to piss her off. Of course. Why should she expect anything less? Lydia had already anticipated this being an unbearably awkward interaction based off the events surrounding the last time they'd found themselves alone together, but she should have anticipated that there was also little chance he'd take anything seriously right now. Even Camelot business. If they didn't need him so badly, Lydia might have killed him.
She almost started yelling at him right then. Almost. It would have been so easy, another bad habit between them that she could slip into like a worn glove. Going from zero to sixty into the middle of a shouting match with Matt may as well be second nature to her for all the time she'd spent doing it over the last eight or so years, but for once, Lydia clamped her mouth shut tightly and took a moment to bite down against her worst impulses, centering herself as best she could under the circumstances. All of that Jedi meditation had to be good for something.
Gathering her nerves together and forcing herself to stay level instead of immediately exploding like part of her wanted to, Lydia fixed Matt with a look that spoke volumes of how unimpressed she was and squared her feet like she was preparing for battle. With Matt, she often was.
"Is this how you normally respond to someone when they're offering you an opportunity?" Her cool, down-to-business tone was deliberate, knowing it often needled him more than her screaming at him did. "If so, it's no wonder your time with Camelot hasn't included many promotions, despite your exemplary record."
Something about the all too casual way he was behaving just got under her skin. As if her being here didn't affect him anymore than her reason for it seemed to. What annoyed Lydia the most was that he was perfect for the job, and she knew it. That was the only reason she was here and not telling Daniel to go to hell. A twisted part of her thought, obviously foolishly, that she could get through to him. That by her being the one to offer it, he shouldn't decline on her account? Considering Leia's track record convincing Han he was destined for leadership, that hope was premature at best. "Would you like me to continue or shall I just tell Daniel that you were too busy laughing to yourself to hear the offer?"
