#2. Lana-Bobby Lashley
This one took fans by surprise when it first happened because of how random it felt. Rusev was in a storyline where he was first revealed to be the father of Maria Kanellis' baby (something she later told Mike Kanellis wasn't true). Interestingly, the Maria-Mike baby storyline had no payoff as well and would kickstart the feud between Bobby Lashley and Rusev.
At the end of September, Lana would return and so would Bobby Lashley, with both of them kissing on stage in front of a distraught Rusev. It began a controversial feud, one that was heavily criticized by fans. As he always has, Rusev used the situation to turn himself into a big babyface and it was going surprisingly well until Lashley kept beating him repeatedly.
Due to Rusev's injury, the storyline had no payoff to begin with and the idea was supposed to be to get Rusev over big. It even acted as the story for Liv Morgan's return, but nothing much came of it.
Lana and Lashley, despite posting on social media, were never together.
