I love how this is framed as if Weyoun is some incredibly important character making his Dramatic First Appearance and the audience is supposed to react like, “Oh shit, it’s him!!” but when he was cast Weyoun was just a one-off character who died at the end of the episode, but Jeffrey Combs played the part so well that the writers ass-pulled the whole “all the Vorta are clones” thing just so they could bring him back, and then Weyoun became a hugely important and massively popular character, so now if you watch this episode for the first time as a new fan, knowing how important Weyoun becomes, this scene does then become the “Oh shit, it’s him!!!” moment it was never meant to be.
