Other mistake: When Jack logs into Lauren's e-mail account, for one, the birth dates on Lauren's IDs say 1959 and 69 (which would make her either 33 or 44). Plus you can see (possibly) real e-mails from actual crewmembers, for example at the bottom you can see "FW:Photos for Alias Ep.#315." (00:10:57)
Continuity mistake: At the beginning of the episode Sydney has a fringe. In the next scene she's shown with no fringe.
Chosen answer: It does sound overdubbed, but there was no change in the organization. UCO is United Commission Organization. There are signs when Patel is coming that say UCO so obviously it wasn't changed.
