#1 Potential mixed tag team feud
The final match of the night was for the Universal title where Baron Corbin got another opportunity at Seth Rollins' belt. And the odds were stacked against the Universal Champion after Corbin announced that Lacey Evans was to be the special guest referee of the match.
Evans had faced Rollins' girlfriend and RAW Women's champion, Becky Lynch, and had lost the match, which meant that Evans had some animosity against Rollins. Evans did everything in her powers - slow counts, changing the match to no count-outs and then no disqualification, and it seemed like Corbin would steal one.
But Becky Lynch came to the rescue of Rollins, and after another referee was sent in to officiate the match, Rollins won the match and retained his title.
This feud could possibly set up a mixed tag team match for the next PPV, Extreme Rules.
