The young woman who Luke hit with his car introduces herself as Jade Taylor; she somehow mysteriously managed to survive being hit by a car (not to mention apparently nearly dying by the side of the road) with no injuries at all and is released from the hospital later that night. When the Snyders take her back to the spot of the accident so she can find her belongings, she admits that she's been watching them for weeks, then claims that, by looking at Lily, she is looking at her mother's face.

Holden and Lily are initially skeptical, even after Jade shows them documents backing up her story, but by the end of the clip it's pretty clear that Lily is hoping it's true because it would give her another connection to Rose.
