Oh, that's great. The last line is perfect---I think that's exactly how they'd both react. (They'd both think that they'd kept it so under-the-radar that no one else would know, or care. Aren't they cute.) I don't know about the 'caring', but the knowing is certainly there.

you know, the more I think about it, this is what we're all really missing--not so much others' reactions to the relationship, as much as J/D's reaction to their reactions. Because they were so hopelessly clueless. So cute.
