through several context clues, I think i pieced together the series of events leading to their capture.
1: The three main scouts Nikos Ruby and uh.. the third guy go out to look for.. something. be it people or vampire nests.
2: The three are spotted and are very actively chased.
3: Ruby shoots one of the vampires in the eye with a gun.
4: All three are captured, and interrogated.
5: (in my case) The three resist interrogations, and die.
