#4 A Becky Lynch loss
The match at Fastlane against Charlotte could be Becky's last chance at going to WrestleMania, at least in kayfabe terms.
The match which was supposed to be for the RAW Women's Championship is now instead going to be for Becky Lynch's chance at competing for the championship at WrestleMania.
Stephanie announced on RAW that if The Man loses against Charlotte, then she is out of the match at WrestleMania. And, if Becky wins, that match will be a triple threat.
The rumors have been going on for some time, so a Becky win is almost guaranteed. But WWE can always pull the fast one and have Becky Lynch lose against Charlotte at Fastlane. That move would get Becky Lynch the sympathy from the crowd, and she would have to further fight her way for a chance at WrestleMania.
WWE did something similar to Daniel Bryan a few years back, having him face Triple H at WrestleMania and then Batista and Randy Orton for the championship later in the night.
