"Oh," Derek says after a long moment. He isn't sure why Bitty is so embarrassed, and he reaches out to hook a finger under Bitty's chin to lift his head. Derek isn't terribly surprised by the information, and it does make him feel good. "Can I tell you something?"

He waits for Bitty to look up at him, and Derek smiles indulgently at him, with an unmistakable warmth in his eyes. "Back in that other place, after-- when you were saying all those things. I almost kissed you then."

It's easy enough to admit, and Derek smiles at him. He hadn't done it because it hadn't seemed right then, and maybe it isn't right now, but there's no reason for Bitty to be embarrassed by this, or to feel bad. "So how about I kiss you now, and it isn't because of this," he says, gesturing up at the mistletoe. "It's just that kiss, but delayed a bit."
