It's been a while since we've seen one of these type of angles in WWE, but it looks like they're setting up a "did she, didn't she" storyline with Lana.
Tonight on SmackDown LIVE, Rusev demanded answers from his former friend Aiden English after lat week's betrayal, and after beginning with the usual "I made the team successful" stuff, the Sultan of Song dropped a bombshell by insinuating that he slept with Lana in Milwaukee.
Rusev didn't believe him, but they're obviously going to play it up that he has some doubts in the coming weeks.
Who knows, maybe it'll turn out that The Ravishing Russian (well, ex-Russian) did bang English and there's a heel turn on the cards.
