The rest depends on how much Aaron wants to involve the Courier. I am under the impression that Courier involvement is being kept to a minimum (pretty much limited to chasing Ulysses) so as to avoid contradictions and prevent people from making claims involving the Courier that don't really make sense or fit with what has been decided for the plot. Like, it'd be weird if one player claims the Courier helped the NCR, and then another player says the Courier helped the Legion. To avoid that, I figured we'd be limiting Courier involvement to following Ulysses. But again, it's up to Aaron. We'll see what he says when he's back.
