The line was a topic for discussion backstage as WWE chose to bring Lana back realigned with Rusev. WWE really had no choice once TMZ leaked they were engaged in real-life in the midst of a love triangle storyline with Dolph Ziggler. This resulted in heat on Lana - as well as another issue where she claimed Paige bullied her during their time in developmental.
Regardless, Rusev and Lana were seen as a major success together but failed once split, so reuniting them not only made sense after the leak and it is probably what is best suited for their on-screen characters. The note to make is the not-so-subtle dig about Ziggler “going all the way” with Lana, which is par for the course in terms of WWE and their backstage politics.
