The second time they're interrupted, it's nearly two weeks later.
Life being what it is for the Legends, the team's been busy. Sara's captain now, and she has a whole new set of duties and possible distractions. She's tracking aberrations and planning operations, and there are nights she can't manage much more than to make it back to her room and collapse on the bed. (And it doesn't help that the rest of the team doesn't seem to think that captains need privacy.)
Leonard's been submitting with ill grace to a set of tests by Stein and Ray, who are fascinated at the notion that someone could survive in the time stream. And he's dealing with Mick, who's not at all interested at this point in going back to their earlier dynamic (fine, because neither is Leonard) but is oddly determined to make sure his friend and former "boss" fits back in with the team. That leads to a number of awkward dinners with Amaya Jiwe, and belatedly to Leonard finding out about his past self and the Legion.
He... has some trouble with that, not the least of which is that he doesn't remember a goddamned thing about it. And he really doesn't like that Amaya, who seems to mean something to Mick, keeps looking at him like he's going to attack her at any given moment.
Like he's his father.
It's not Leonard's way to pussyfoot around... well, anyone, really... but for Mick, he tries. He's really rather sincerely interested in Amaya's background with the Justice Society and her general badass-ery, and that makes it easier to turn on the charm. But she keeps giving him that look, and in frustration the snark edges back into his voice, and the whole thing goes downhill from there.
Annoyed, disgusted with himself... especially his past self... he stalks back to his room, fuming and wondering if he's ever going to truly make this work.
And there, he finds Sara, waiting for him.
He stares at her a long moment; she holds up a bottle of Scotch and a pair of glasses with a grin. But the smile slowly slips away, turns into something a bit more intense, as he takes one step toward her, then another, and she set the glasses and booze down a few seconds before he finally reaches her and they crash together in their third kiss since that fateful day at the Oculus.
It's messy and passionate, utterly unlike the goodbye of their first kiss and the promise of their second. Len's hands are tangled deep in Sara's hair; her nails are digging into his scalp, fingers flexing as they mutually deepen the kiss. After a minute or an hour, she breaks away with a noise of frustration at the height difference; he responds by boosting her up against the edge of the bed and going in for another kiss. She gives in to a very long-standing impulse and shoves her hands into the back pockets of those damned skinny jeans, pulling him closer even as she tucks her knees around his hips, appreciating the almost-growl he makes as the last iota of space between them vanishes.
In reality, they get maybe a few minutes. Then the spell is shattered as Mick—damn him—pounds on the door, bellowing for Snart and demanding to know what he'd done to upset Amaya. And Mick, they both know, will not accept silence or excuses as answer.
They break apart with regret, again; lips swollen, Sara's hair mussed and both of them breathing heavily. Len shouts for a moment's grace, thinks regretfully about a cold shower; Sara twists her hair back in a knot and smirks at him, just a little. She whispers in his ear before he opens the door; he nods seconds before she slips out, stepping around their teammate with a nod. Mick blinks at them, surprised but patently unfooled, even as he chooses to not pursue it at the moment.
Sara makes her escape; Len turns to face his friend. And while it might not have been the evening he'd hoped for a few moments ago, at least they manage to hash some things out before they go their separate ways that night.
