"Hey," Ed answered the moment Chuck peered into his room. After all his travels, he knew better than to trust someone just based on how they looked -- but she didn't look too terribly threatening.
And she didn't look too squeamish either, which was pretty helpful. Ed had gotten somewhat used to being the only person in the room wearing automail (even if he did hide his fairly well) but there were also plenty of people who wore automail where he was from. Here, he hadn't seen anyone else wearing it, and it seemed to confuse most people when he mentioned automail. For whatever reason, it was unique to where he was from. But Chuck didn't stare overly much at his empty ports, which helped to reassure him. A bit.
"Yeah," he answered, nodding toward where his arm and leg were resting. "Just easier to have someone line them up for me." The last thing he needed was to not connect them properly. It was hard for him to cinch them in place with the jump to his nerves. Made his grip slip.
