Harry's brow furrowed in puzzlement, knocked off the rails of thought by the slight snag; he could've sworn he'd already shared that piece of information, but then again there was usually so much going on in his head at any given time it was a wonder even half the stuff actually managed to find its way out. "...You didn't? Thought I said as much already. I mean, I ain't anymore, since they kinda have rules 'gainst lettin' people of my particular mental status fly, but. Used to be, though, an' I'm pretty sure I still could if I had a bird t'prove it. It's like ridin' a bicycle; once you know how, you don't forget." He swelled with pride during the explanation, only deflating slightly when he got to the part where he wasn't allowed to fly anymore; his grandma had always said he was half bird, and to a degree he was inclined to agree (he'd always felt more at home in the sky - up there he could be graceful and free and in control, on the ground he usually just felt awkward and clumsy, like a penguin on dry land), so having his ability to fly just stripped away from him like that was tough, even ten years later.
Harry stood when Tim did, grinning widely. "No problem; I had fun too. We should do this again sometime. ...For real, not just talk about doin' it an never get around to it." His words held none of Tim's uncertainty; the evening had been fun, and he'd definitely enjoyed Tim's company, and, well. Harry never had really been hung up on the whole...gender thing; personalities were way more important, and he liked Tim's. Liked it a lot (and yeah, the outside didn't hurt either). So the idea that there might be a second night like this...well that was just a given that there should be.
...Even if he had made him wear uncomfortable clothes on the first date.
