#2. Lashley stands tall after the divorce is official
This is a likely scenario if the match ends up going through and is announced for TLC. The segment should be a double-signing for Rusev, having to sign for his divorce as well as a TLC match against Bobby Lashley.
If that is the case, it's hard to imagine Rusev standing tall. For one, it's the go-home show, which means that the loser of the blowoff match usually stands tall. It's wrestling 101. There's no way that the payoff involves Lashley winning unless they plan to extend the storyline until a later point, i.e, the end of the year or Royal Rumble 2020.

Secondly, Rusev's popularity has surged since this storyline, no matter whether you love it or hate it. The numbers prove otherwise and Tom Colohue even reported that Rusev has gotten a lot of praise from Vince McMahon for this storyline and the favorable reactions it's produced.
WWE listens to these reactions and when the numbers back it up, they will continue the story. Either way, expect the divorce to go through and for Lashley to stand tall with Lana at the end of it.
