WWE Fastlane 2019: 5 things you need to know before the PPV

#3: Will the Shield implode?

Ambrose betrayed the group in October, after Roman Reigns announced his leukemia diagnosis.

The odds may be in the Shield's favor, but that doesn't mean things will be plain sailing.

After all, the trio of Reigns, Ambrose and Rollins only reunited last week, after Ambrose turned on the team in October, the same night that Reigns forfeited the Universal Championship.

We don't know what's going on in the three men's minds, but it wouldn't be farfetched to assume there may be some tension between the trio after all these years.

Rollins infamously turned on the group in 2014, though has his ticket to WrestleMania already punched, as he will face Brock Lesnar for the Universal Championship.

With Reigns and Ambrose both still without a match, could we see the two team-mates implode tonight, and face off against each other on the biggest stage of them all?
