For most of this episode, Duchess Satine is wearing an elaborate headdress:
When Tal Merrick* takes her hostage, however, he knocks her headdress off:
When it appears as if Merrick is going to escape with her as his prisoner, Satine confesses her love for Obi-Wan: "Obi-Wan, it looks like I may never see you again. I don't know quite how to say this, but I've loved you from the moment you came to my aid all those years ago."
Satine's headdress represents the hidden nature of her feelings. Only after it's been dislodged are they exposed.

*There's some discrepancy in how Merrick's name is spelt. In the credits, it's Merrick, but on the Star Wars website, it's Merrik.
