At least Echo tries to be thoughtful. Obi-Wan is still a little startled though when he hears the unmistakable voice of a clone trooper. He looks up to see the man standing at a distance, something he's certainly grateful for as he rises to his feet. There's a wary look to him. While he had served alongside clones for years in the war, they had suddenly turned against him and the other Jedi. Still, there was no aggressive moves being made here, which caused him to look the trooper over more carefully.

"Echo... is that you?"

That's one he hadn't seen in some time. Hadn't he been killed? But he was the only ARC Trooper to have that hand print on his armor.
