#2 Charlotte pins Bayley with her foot on the rope
To help protect the validity of Bayley whilst also keeping Charlotte dominant, an inconclusive finish must take place. Bayley getting robbed of the title she's worked so hard to gain would evoke a lot of sympathy from the WWE Universe.
On the flip side, Charlotte regaining her coveted title by not truly beating Bayley would draw enormous amounts of heat, heat that a heel needs. It's a win-win scenario that creates more tension for their expected WrestleMania bout.
The PPV before WrestleMania is always used as the event to set up major storylines for the show of shows. Fastlane should leave stones unturned and cliff-hangers present for Mania.
This scenario is perfect, Charlotte goes into WrestleMania with her streak still intact with Bayley looking like the ultimate underdog.
