Biography
It is believed that Marla is the daughter of Benjamin Dwayne. By the second episode of the series, she is marrying Ted Vienna, when her friend, Francine (whom is a secret agent as well), approaches. After some light chat, they mention the odd music the band is playing. Ted then leaves, Francine in hot pursuit. However, Marla just stands there, as if hypnotized, or as if she is no longer truly conscious. Nothing is known about what happened to her after that.

Behind the scenes
Some theories suggests that Marla Dwayne and Deborah Pan are the same person. Having one hour between Marla's first appearance on the show and Deborah's first, could leave time for someone to lock her in her house and trick her mind. This could be what the music did.
