Also, I think Yueh was the worst written character in the two movies. They really glossed over him and his return in part 2 felt hollow.
The Dr guy that got killed in part 1? I don't think he was in this at all, but I could be wrong. If you're referring to the Asian guy in the coloseum scene, I think that's actually Lieutenant Lanville who was Gurney's #2 in the army.
