As he came back to himself, Steve's eyes were resolutely focused on the reactor in Tony's chest. His soulmate's chest. Since they found each other, they were only longer alone, now finally a 'we'. It would be an adjustment for Steve, along with everything else since they unfroze him. But they all promised he would acclimate in time and the constant chill would leave him. The fact Fury wanted to give him a mission already spoke volumes of his 'adjustment time'. Would he be able to bring along Tony? Apparently, it would be an undercover mission and would take him to a cabin. On paper it looked like a rather simple mission but he knew better than to trust that.

It worked as a pacemaker? Shrapnel in his chest? A frown tugged at his lips as he considered it all, his fingertips tracing along the edging again. "If something happens to this reactor -" He trailed off, the thought making his stomach sink. Of course life decided to give him a soulmate he could lose at any moment. No need at all to be on constant edge.

"Did you make it? Design it I mean?" It seemed like something Howard would have developed and Tony being his son and all.

Touching Tony made him feel better he realized and far less cold.
