Tony | Superman
Clark merely nodded at him. It sounded like he cared a lot about what Steve thought. He wondered how much of Tony's own denial was a self defense mechanism or if he just needed to keep up an appearance for fear that someone might see past the armor he had built around himself. He didn't want to tell the kid what to do because... Well, mostly because that never worked out well. So, instead, he did what some of his therapist friends did.
He asked Tony: "And how does that make you feel?" Because, ultimately, Tony needed to be able to figure this out on his own. Plus, he was sure there was more going on than just how he was nervous around Steve.
