Entirely valid concern. They could write it into the charter. Tony crossed his heart, promising to keep all of his spider-jokes to himself as long as Jess was in the room, but he couldn't promise it would hold up when she wasn't. He was sure Spider-man wouldn't mind the implied relation so much, even if he didn't measure up. She'd have to pass that along to Cap herself, though, because Tony had a flight to catch. "Get some sleep, sweetheart," he said, bowing to kiss her temple appreciatively. Not just then, but she could try getting into the regular habit while Tony was away. If not for herself, then for a team that could really use a full charge from their scattered numbers.
