Ives and Colqhoun
So was "Colqhoun" Ives all along, or is Colqhoun his real name and he just took up Ives' identity after killing him? We know there was a real Ives due to nobody asking questions about Colqhoun/Ives when he turned up, and because of the uniform Reich and Boyd find in the cave.
When Colqhoun/Ives tells Boyd his backstory about how he used to have tuberculosis, he never mentions which identity is his real one. So either he was Ives all along and killed the entire party, then impersonated Colqhoun briefly to lead the soldiers into a trap, or he was Colqhoun and just took up Ives' identity.
But the question is which is true?
