I'm missing something here. Why are we so sure that Ulysses is the other Courier?
Ulysses is on a card in the
Caravan Deck we got with the
Collectors Edition of New Vegas.On it is a man with a vest that has the
old united states flag on it.
At
Nash we get to hear that
another courier was suppose to take the delivery of the
platinum chip but changed his mind when he saw
"The Courier's" name and asked if he was still alive to which Nash replied "yes".
He then left and said "
let Courier Six handle it".
Then in
Dead Money we can get an ending slide or a dialogue option with
Christine where she explains that she was once helped by
a Courier with "the old worlds flag on his back".
This courier which helped her was looking for "
another courier".
And then in
The Merge's ending slider it says that The Merge did not hear more of
"The Courier" (The player character) until he heard tales of
The Divide where TWO couriers fought together/against each other.
