Unlike the shocking, graphic death of Tom Yates, LeAnn Harvey's (Neve Campbell) fate is left a little more ambiguous. At the end of the season, the former Underwood campaign manager gets pushed out of her role in Frank's administration because of her involvement with Aidan Macallan's scheme to help the Underwoods rig the election. Fortunately (or rather unfortunately, later on), Aidan sends her evidence files before his own death, giving her some leverage to work with.
In the season five finale, LeAnn decides to make use of the little leverage she has by handing the files off to Jane Davis, who promises to make her Claire's chief of staff in exchange. Mark Usher throws a wrench in their plans when he kicks LeAnn out of the position soon afterward, and Jane is forced to admit to Frank that Aidan's files are now in Claire's possession.
All of this leads to Frank declaring that "LeAnn's job is done," implying she's going to bite the big one. Next thing we know, she's driving her car at night and driven off the road by another aggressive vehicle. The camera cuts back to Frank, who does one of his trademark looks to the camera before saying, "Sometimes you don't have to watch the whole movie to know how it ends."
A quick shot of her mangled car in a ditch is later shown, implying that she dies even though we never see a body. The situation is reminiscent of the season two cliffhanger involving Doug Stamper, who's left to die with a seemingly fatal head wound in the middle of the woods, though he pops up alive in season three. It's probably a safe bet that LeAnn's fate will be something similar.
