Sure enough, Mark buys her a drink as soon as they arrive, and they're making out maybe twenty minutes later.
Callie is so hungry for sensation, all of a sudden. With two drinks in her, she feels tingly and heavy at the same time, and she wants Mark's hair underneath her fingers, his lip between her teeth, his chest against hers. She's half in his lap by the time the others come to join them on the bar's lounge chairs, but he gracefully slides out from under her just before they arrive.
Addison sits across from them, eyes on her phone. Cristina and Teddy sling themselves on the couch to Mark's left, chattering away.
Erica sits to Callie's right.
Callie keeps her hand on Mark's knee, leans into him, plays with her hair with her other hand. She doesn't answer when Erica says hello, or when she asks how Callie is doing. Instead, Callie keeps her eyes on Mark's face, giggles at what he's murmuring to her.
She ignores everyone else too, just to be fair. Even though a sting of guilt, muted by the alcohol, is telling her that this isn't fair at all.
After a minute or two, she hears Erica shift away and strike up a conversation with Addison. She tries to listen while also half-listening to Mark, which predictably means she can't hear anything. Mark realizes this eventually, swats at her thigh playfully. She catches his hand and holds it against her leg, hoping that it'll help her heartbeat slow down.
Then, an unknown amount of time later, she hears Erica say: "Okay, I'm going to get another drink."
Feels more than hears her scoot closer.
Erica's voice, a little louder: "Callie, do you want to come get a drink?"
Callie's mouth is so sensitive right now. She doesn't respond.
"Callie."
A new edge in Erica's voice. Finally, Callie manages to unstick her clumsy tongue. She turns towards Erica as though she just heard her, but still can't bring herself to look her in the eye.
"Nah, I'm good here," Callie says, doing her best to sound casual.
"No celebration drink? I'll buy you tequila shots," Erica says, playful again.
Rage spikes through Callie abruptly, because how can Erica pretend this is funny? They can't just drink tequila like it's one of their usual nights out. Everything is different now.
"I said no thanks, Hahn," Callie bites out, glaring at the floor.
Erica is still for a moment. Then out of the corner of her eye, Callie sees her get up and leave.
The night passes slow and fast at the same time. Callie gets drunk and dizzy, all her muscles are sore, and she wants to go home but can't stand the idea of being alone in her room.
At some point she sees the team doing body shots, which is a tradition she normally loves, but this time she watches instead of joining in. It's a set routine, the same every time. Tonight Izzie takes a shot off Meredith who takes a shot off Cristina who takes a shot off Teddy who takes a shot off Addison who takes a shot off Erica - and Callie is so fucking like blisteringly frustrated watching Addison lick around Erica's collarbone, tug a shot glass out of her cleavage with her teeth, and suck on the lime between her lips that she can't even watch Erica do the same thing to Miranda.
Instead she turns her head to see Cristina and Teddy making out, which is not exactly surprising; they've been dancing around each other for months. Callie has no idea why they waited this long - plenty of people on the team have dated or hooked up, and the two of them are more likely to make it last than most.
She's happy for them, and then she starts wondering who on the team Erica has hooked up with, and she's so weirdly upset by the idea that she has to kiss Mark again to make her brain quiet down.
This time, he lets her straddle him.
(After the shots, Erica and Miranda stay by the bar chatting. Erica thinks they're not quite friends, but they respect and trust each other and often end up having long conversations at team events, so maybe they are friends, actually? She's not great at parsing things like that. Maybe she should invite her over.
Izzie comes up to the bar to get another drink. After she orders, she says to Erica brightly, "I didn't know you and Callie were together!"
"We're not," Erica says flatly. "Haven't you ever seen people celebrate winning?"
Izzie's drink comes. She toasts to Erica drunkenly and swallows half of it in one gulp, then wanders off.
Erica can feel Miranda staring at her, and she tries to ignore it, but after a minute she snaps. Another sign that they might be friends: Miranda knows exactly how to get to her. "What?" she asks belligerently.
"Don't tell me that kiss didn't mean anything, and don't lie," Miranda says.
Erica wants to deflect, she really does, but she's tired and tipsy and Callie isn't speaking to her. So.
She sighs. "It didn't mean anything to Callie," she says quietly.
"But it meant something to you?"
The pity in Miranda's voice rankles, but not more than anything else tonight has, so Erica just shrugs. "It shouldn't, so…want another shot?"
"Sure," Miranda says, and Erica orders them another round).
