Rory wasn't at all offended by Gio's secret-keeping. After all, he was doing the same thing, especially since one of the names he was keeping a secret was Eisen's. He was fairly certain that his best friend wouldn't mind that much if he told his brother, but Rory was too loyal to do something like that without asking him first. Besides, sharing one name might obligate Gio to share one too, and that wouldn't be fair. It was better to keep everything relatively anonymous. For now.
"Oh I don't know about lame. Hey! Maybe that my power. I am obviously the lamest of the lame." Rory rolled back and forth in his wheelchair a few times to prove it, grinning in amusement to keep Gio from feeling uncomfortable. When he'd first been put in the chair, "lame" jokes had always made him quiet and depressed, but now, so many years later, he was making them himself. Deep down there was still a little part of him that stung, but it wasn't strong enough to pay attention to.
"Come on Gio! Gills are totally better than a snorkel. You could stay under there and talk to the fish a lot longer anyway." Rory's phrasing was very specific; given how often Gio actually spoke out loud to his fish, Rory sometimes joked that he was actually carrying on a real conversation. He even went so far as to (occasionally) refer to Gio's collection of fish as "the philosophers," amusing himself with irony, given the famously short memory of fish.
Rory thought about it for a few seconds. "No... I don't think so. I'm pretty sure I'd know if I were hearing other people's thoughts. But thanks, Gio. That's a high compliment."
