Just finished watching Apocalypse Rising from the 5th season and something bothered me about the entire plot. It's the ep where Sisko, Odo, O'Brien and Worf go undercover as Klingons to uncover the Changeling. Anyways...Sisko, Odo and O'Brien are all disguised as Klingons. Yet Worf isn't disguised at all. How does it make any sense to send one of the most well-known Klingons on this mission? Why didn't anyone notice him as being Worf? Why would Changeling-Martok be able to recognize Sisko as a Klingon but not an undisguised Worf? Am I missing something here?
