#3. Money in the Bank contract

After a fantastic WrestleMania event, WWE's next pay-per-view stop is Money in the Bank. The company aired a promo to hype up the upcoming show during the second night of WrestleMania 36. Hence, the WWE Universe could see qualifying matches for the multi-man ladder match soon, and Lashley could be one of the competitors.
WWE could progress the storyline of the rift between Lana and Lashley in this race. For some reason, the Ravishing Russian may miss the RAW episode, where Lashley would compete in the qualifiers. The Dominator would win that match and secure his berth in the Money in the Bank ladder match.

Then, during the main bout, Lana would accompany Lashley to the ring, costing him the victory once again. Since this win could have changed the All-Mighty One's career forever, he would lash out on Lana, leading to the end of their relationship. Given that WWE needs to boil up the matters before the big break-up, the writers could take this route.
Lashley and Lana will likely split soon. WWE needs to make sure that when they lose their cool, the audience should receive a shock, just like they were amazed when the two appeared together on RAW.
