WWE Fastlane 2019: 5 shocking ways to end Becky Lynch vs. Charlotte Flair 

#3 Ronda Rousey attack on both Superstars and the match ends in Disqualification

This could happen as well

Recently, Ronda Rousey turned heel against Becky Lynch when she mercilessly attacked the former champion without any signs of stopping the attack. I think that at this point, when we are just a few weeks away from ‘Mania, WWE won't take a chance in damaging Lynch or Flair’s momentum. And, if that’s the case then Ronda could help in ending this match.

As she is already a heel, we could expect her attacking both Superstars at Fastlane just like Lynch attacked her and Flair a few weeks ago. I think the Raw Women’s Champion will attack The Man first as this way, she will get added to the ‘Mania match and it will also make the Lynch’s injury saga more interesting.
