10 New Directions For WWE After SummerSlam 2018
7. Becky Lynch Challenging Charlotte
What Happened At SummerSlam: After sticking her nose into Becky's business, Charlotte Flair ended up stealing her friend's thunder by hitting Natural Selection and pinning her to become the new SmackDown Women's Champ. Afterwards, Lynch smacked Flair around and (sort of, but-not-really-according-to-Brooklyn) turned heel.
Where It's Going: Becky will blame Charlotte for intruding on her shot at Carmella and scooping the acclaim for herself. There's at least one angry promo coming from Lynch that tells how Flair has ruined her dreams, and not for the first time. There's no way they're staying friendly after the kicking Lynch gave the new champion.
If WWE want to book 'Champ vs. Champ' and put Charlotte against Ronda Rousey at Evolution, then they've got a sweet placeholder feud for Flair in the interim against Becky. They've always had good matches, so quality wouldn't be a worry despite the brief nature of the feud.
Besides, they can pick it back up again post-Evolution.
