One thing that strained credulity for me a bit this episode was how "Yes, I am the Emissary" was good enough to give Jod access to one of the vaults. I mean, yes, it's relatively safe to assume that a person who passes through the Barrier in a Republic Emissary vessel would be a Republic Emissary, but given that we're talking about lots and lots of money here, you'd think the Emissary would still have to show some kind of ID ... or have a special key needed to unlock the vault ... something like that anyway!
