#3 Tegan Nox
This is the storyline development regarding Dakota Kai. As of right now, Tegan Nox has not yet returned to NXT following the betrayal she suffered at the hands of Kai. The former Nixon Newell "re-injured" her knee during the beating she endured at NXT Takeover: War Games 3.
It seems a likely shout that Nox will play a part in the Royal Rumble match, possibly eliminating Kai and setting up a grudge match for the black and yellow brand. After all, Superstars returning from injury are always welcome in the Rumble match.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
The Welsh-born Superstar has had some horrific luck with injuries in the past and now, it looks like those days are over. Hopefully, once she is back, Tegan Nox can return to form and get going at Full Sail. Returning at the Minute Maid Park could be the start of a truly memorable run for 'Lady Kane'.
The women's Royal Rumble would be better off if the former Team Kick partners have a confrontation during it.
