#4 Lana and Lashley have a wedding
In the complete opposite of the previous entry, WWE could go even further with this storyline and take it up to an entirely different level. The stakes have indeed risen every single week. First there was a kiss, then a trip to the bedroom, and a suggestive massage. After that, it was revealed that the Lashley-Lana relationship wasn't only physical. Bobby had also been taking Lana out to expensive restaurants and she even claimed that they were in love.
Maybe they are. It's possible, especially since this is pro-wrestling we're talking about, that while Lana was originally using Lashley as a way to get back at Rusev for cheating on her (maybe she's being truthful about it). In the 7-weeks that Lashley and Lana have been "seeing" each other, it is not out of the realm of possibility that the two have grown a strong affinity for one another, and they truly have fallen in love.
In the real world, some people really do fall in love very quickly and are married soon after they start dating. In the world of professional wrestling, this process can often be sped up to accommodate the story that is being told. What if, at Survivor Series, Lashley gets down on one knee and proposes to Lana after defeating Rusev? That would cause one heck of a stir, and might even bump up the ratings for the episode of RAW that the wedding is scheduled to take place.
