Steve was about to freak out. Sam was marked by Insight. He knew he had been, but then Steve had also been marked, but he'd been lucky. HYDRA had chosen to try to recruit him, and had succeeded. Maybe the same thing could happen with Sam.

He stepped closer, dropping his voice as well. Sam had to be hiding from the helicarriers, and automatically Steve's eyes rose, though he knew they weren't covering this area at this time. He nodded, covering the gesture with a stretch, and then putting his hands on his hips. "Sure, let's take a walk." He turned to continue the way he had been walking, jerking his head to indicate that Sam should walk with him.
