Sara and Leonard
Leonard prided himself on being a wordsmith of sorts. When he spoke, he had a talent of accentuating that few people possessed and the thief was aware of it. Often, his ability to string words together was used in his criminal exploits and all they tended to be? Flowery language meant on distracting. Leonard could make it seem as if whatever you said was the most important thing to him in the moment even if that was just a mask.
Yes, with Sara they needled one another, but Leonard also happened to be a tad more honest with the assassin than with almost anyone else. Unless that person was Mick Rory. When he spoke those words that clearly left her speechless, Leonard meant every syllable. He'd been with a few women throughout his lifetime, but none of them had ever captured his attention like her. Made him stop and think about the man he wanted to be. Yes, he swore to be the best criminal in existence, but with Sara, he wanted to be something more. The mission had sparked that desire in him, but it was Sara Lance that had fanned those flames.
"I never thought I would see the moment I left Sara Lance speechless," Leonard replied smoothly. Before he could say anything else, she leaned in and kissed him. Leonard was momentarily caught off guard, but like the adaptive human he'd trained himself to be, it wasn't long before he was returning it.
And it also wasn't long until he deepened it. He placed her hand on his other shoulder while his own shifted to land on the other side of her waist. Leonard pulled her flush against him and for the moment, the rest of the world didn't exist.
