"Ah, I see," he nodded. "Would you like to head back that way now, or...?" He left the alternative open, because he really wasn't sure how to talk about his swinging from the trees without sounding like an idiot. Plus, the forest seemed to be making Miguel a little twitchy, a little paranoid maybe. Whatever he was hearing in the woods was a mystery to Darcy - he knew the forest was alive, and that there was always something moving out there, but he was so used to it that he barely noticed most of the time.
He was just nodding along sympathetically, ready to say that he was sorry the station was messing with him again, when his friend dropped something of a bomb shell. Darcy paused for a beat or two, just letting what he had said sink in. He didn't want to react too drastically out of shock, and he was well-practised in keeping something of a neutral expression. If he'd been part-spider the whole time they'd known one another, then nothing was really any different but his awareness of it.
"Um... well, how does that..." he started, not really sure how to word it because his brain was still playing catch-up. "You don't seem very spidery. Well. At least you didn't, until the uh..." he pointed up at the trees, his expression softening into a bit of a teasing smile.
