The rivalry between Seth Rollins and Dean Ambrose is arguably the most personal in recent WWE memory.
With a long history behind them, and with the Roman Reigns illness factoring into storyline, you get a blood feud with big stakes.
It doesn't even a championship to be contested but that is what we've had, with Rollins holding the belt for the second time since SummerSlam way back in August.
Perhaps it surprised many WWE fans though that Rollins failed to give Ambrose his comeuppance at TLC for all his recent attacks, with one Dirty Deeds being enough to start the Lunatic Fringe's second run with the strap.
Ambrose, being the fighting man that he is, issued an open challenge for his gold the following night on Raw, in the hope of luring Rollins out for another match whilst he was vulnerable.
Instead we got the welcome return of Tyler Breeze, who showed why he was such a hot commodity in NXT years back, but obviously wasn't to be successful.
We now know who the next challenger will be though to Ambrose's freshly-won title.
The Raw brand hosted a battle royal which took place at the famous Madison Square Garden last night, and the competition wasn't very star-studded.
Konnor, Viktor, Zack Ryder, Curt Hawkins, Rhyno, Heath Slater, No Way Jose, Titus O'Neil and Jinder Mahal were all participants, but it was Apollo Crews who came away victorious.
Crews last eliminated Mahal to set up a future match with Ambrose, and it won't be his first shot at WWE gold.
A run on SmackDown in late 2016 saw Crews get opportunities at the same title, and although we can't see Ambrose dropping it just yet, it will give Crews the chance to shine against a main event-calibre opponent.
But rest assured Ambrose and Rollins are not finished with each other yet, and don't be surprised to see the two face-off at the Royal Rumble.
