I have to confess I never liked Lwaxana, not in TNG and not in DS9. Having said that, when she wasn't playing her persona, she was very sensative to and quite astute about Odo.

The Forsaken did have some memorable dialog though. The one cited by Kraucik83, and that funny scene in Odo's office when she is coming on to him so strong.

"Been with . . .? about three octaves higher than Odo's normal voice.

For me "Fascination" was embarrasing to watch and "The Muse" made me positively cringe. I thought Odo so OOC in "The Muse," with the exception of that last scene, which was touching.
