She's just... adorable, and Cisco isn't sure she's even aware of it. Which just makes it even better. He notices she's a little flustered but...he doesn't have the pieces to figure out why. He's not too fussed about it, though, as they continue counting the last seconds of the year. "Five...four..."

There's barely any time left and a thought dawns on him. That silly tradition of kissing at midnight. Did they even have that tradition on Earth-2? Would she be weirded out if he tried? "Three...two..." He'll just explain it later if she's confused. As the last second ticks by, he leans in and presses his lips to hers in a soft, almost chaste kiss.
