Edna married Mr. Raines and the two had a child named Annie who was murdered by a serial killer. Edna worked in the Centre infirmary as a physician and was friends with Catherine Parker. It was believed that Edna had committed suicide around the time of Catherine’s supposed death.

In April of 2000, after Miss Parker, Broots, and Sydney discovered that Edna was not dead but very much alive and living at the “Pratt Institute” (which Miss Parker calls an insane asylum). When they try finding her they learn that she’d escaped. After returning to Blue Cove, Miss Parker puts Broots on high alert to find Edna who shows up on her doorstep confused and calling Miss Parker, Catherine. Sydney tells Miss Parker that 20 years of being sedated is bound to have taken its toll on Edna. Miss Parker is convinced there is an important reason that Edna Raines came to find her mother and that the only reason that The Centre would have hidden her away all this time is because Edna knows their secrets. Miss Parker wants to know them, too, and tells Sydney that they should get Angelo to see if he can help get inside of Edna’s mind.

Once alone with Edna, Miss Parker asks Edna why Mr. Raines has kept her “doped up” for the past twenty years … she wants to know what Edna knows … but no matter what Miss Parker says to her, Edna only replies, “So good to see you again, Catherine.” Frustrated, Miss Parker says that she is not Catherine – she tells her that her mother, Catherine, has been dead a very long time. As she walks away, Edna suddenly says, “How are your mumps, little Miss Parker?” Miss Parker asks her why she came to see her and Edna tells her that she came because of “Mirage.” Miss Parker wants to know what “Mirage” is … and Edna tells her that it was her mother’s work — work she’d hoped that Miss Parker would finish. Miss Parker asks her what kind of work it is – but Edna slips back into her non-communicative state – just staring off into space. Miss Parker rushes to Broots, leaving Edna in Sam’s care. When Sydney and Miss Parker return they discover that she has given Sam the slip.

Things get stranger when Miss Parker has Broots start digging for Mirage and a sweeper dies trying to bring her information. Miss Parker also notices she is loosing email and when Broots looks into it he finds a video email and discovers that Mr. Raines has intercepted it. Miss Parker has him go after the email. Once they access the email they discover a video message from Edna to Miss Parker stating that it is time she learned about her mothers work and that she needs to reply to the email so they can meet. She also says it is a matter of life or death which makes Miss Parker wonder if Edna is alright considering Raines got to the email before her.

At The Centre, Miss Parker has received a cyber-postcard from Jarod. It shows Edna Raines, a picture of Mr. Raines, a picture of Catherine Parker, a picture of a building and a picture of Miss Parker as a child with Catherine. Jarod narrates the post card – saying that now that Edna has escaped where her husband has kept her captive for so many years, she has something that she wants to tell Miss Parker about Mirage” and that she will consider it her redemption to tell Miss Parker. However, she can’t “come home” because there are too many sweepers looking for her. The message that Edna passes along is that no matter what happens, she wants Miss Parker to keep digging for the truth – the secret that her mother wanted her to find is buried out there.

Miss Parker, Sydney and Broots finally locate Edna, but it is too late as they walk in on Mr. Raines putting a sheet over her body. Raines claims that Edna took her own life but Sydney isn’t buying it.

The clues Edna left for Miss Parker led her to discover that her mother didn’t die in the elevator but was killed by Raines after giving birth to Ethan.
