Much as he wanted to address the problem of her knowledge, he was cowed by her insistence to carry on in spite of injury. He did not perhaps feel guilty, but he certainly felt shamed. Battered as she was, Peggy Carter was continuing the mission. He could scarcely stand behind while she dragged herself into the mouth of hell. So despite intending to hold his ground, he finally yielded and fell into step behind. Free to move at his own pace and maintain his own balance, it was easier now for him to navigate his way down. He could have easily moved on ahead of her, but he kept his eyes glued to the back of her. She was in no right state to be handling this on her own.

He said nothing, though. Aside from pressing the point of his secret, there was nothing to be said. For now, the mission and survival had to continue. Perhaps by the time they found somewhere to rest, she might have enough wits to come around to his way of thinking. He didn't see how she had much of a choice in the matter.
