She was so tempted to tell him he could leave it. That, however, would be rude. And yes, she found it very laughable that that was a concern at the moment. Hell, he was checking up on her even if it was the last thing she wanted right now, but he'd had the good sense to bring booze when he did so. That didn't deserve a kicking out.
Especially considering she knew how much McCoy loved his Bourbon, and this was nonreplicated. (Really that was a very generous and touching overture in itself.)
She tied the tie around her waist since he'd be staying. "Sit down." She offered. "Though I warn you I'll probably be rotten company." she tagged on wryly. She went to a cupboard and grabbed two glasses from it. She sat them on the table and sat down across from him. Once he'd poured she took an extremely healthy gulp from her glass, making just the tiniest of faces at the burn.
But really she didn't have much of anything to say. She was still flipping through it all in her head. "Thank you." she said looking into her glass. "It was nice of you."
