Normally, he would probably be able to sense the anxiety that his sight caused. He'd seen the tension in her form, but that was the extent of his perception. He'd been too busy from the moment he arrived on the other side to even find the right mirror to keep an eye on what his alternate had done, so he really had no clue what Natasha had put up with. Or Bucky, for that matter.

Any injuries he sustained on the other side were healing slowly thanks to the current. Still faster than humanly possible, but bruises would probably still leave some discolouration if one was looking closely enough. He could imagine, if she had just happened on his doorstep after he got back in, he would have been tense at first, too.
