Millie Winchester is a main character in The Winchesters portrayed by Bianca Kajlich. Millie is "hard-working and tough and has done the bulk of parenting in her family for the past 15 years. She has always worried John, a Vietnam veteran, would take after his father and wanted to prevent him from pursuing a dangerous life. She is now coming to grips with the fact that this is exactly what John plans to do."[1]

She is an alternate version of Millie Winchester from the Supernatural series.



Physical appearance[]

Millie is an adult woman with fair skin and long brown hair.

Powers and Abilities[]

  • Expert Mechanic - Coming from a family of mechanics, Millie is an expert at repairing things, cars in particular. Over the course of just a couple of days, she was able to repair Mary's car which she described as being "trashed." After the Ostium is broken, Millie takes it home with her and attempts to repair it despite the fact that it appears to be broken beyond repair. Although unsuccessful at first, Millie actually succeeds in repairing it eventually, resulting in pieces of metal around the box presumably helping to hold it together.





  • Millie sold her wedding ring to repair the hydraulic lift in her garage.
  • In Cast Your Fate to the Wind, Dean says in a voiceover that his dad used to say, "Fate is what you make it." Later in the episode, we see Millie say it to John, so presumably, when John from the main reality was saying it to Dean, he was quoting his own mother too.
  • In the same episode, Millie mentions that the engagement ring John gave his ex-fiancée, Betty Donelon, belonged to Millie's grandmother.
