Steve felt like with this Tony he could see tiny glimpses of what his own Tony might have been like when he was younger, before he was so practiced at everything. He knew they weren't the same, they came from different places and had different experiences but there was just something charmingly Tony about him.
His own Tony certainly didn't blush and Steve laughed, gently and not at all unkindly. He'd taken a chance assuming Tony had feelings for Steve, but it had seemed pretty clear. It was wonderful really to think in another world, two different Tonys both liked their own Steves. It gave him hope that maybe they really were meant to be and that they weren't simply waiting to be torn apart again.
"I taught my own Tony how to fight out of the suit," Steve explained as he unwrapped his hands, sure if he'd split his knuckles on the bag they'd have healed but if he could avoid it then he would. "We spent a lot of time training together." Even in the darkest times Steve looked back fondly at how they'd bonded in the ring and how it had driven him crazy fighting when he'd wanted nothing more than to touch him gently. "I can teach you a few things."
