During your trip in the Vietnam jungle, you spot two soldiers conversing. One of them seems to be a friendly U.S solider, while the other one looks like a vietcong soldier.

Ashley: What a convincing disguise! It's almost as if you took it from a dead soldier!

Andrew: Shut up...why are we doing this anyway?!

Ashley: Hahahaha! Lighten up a little! No one sees us anyway, so shut up and pretend I'm a prisoner!

They don't seem to see you, and your interaction with them may not keep your health in a good condition.
