I haven't watched a NXT start to finish for a minute, but, wtf?!
Ridge is in Chase U?!
So Ridge was moping around backstage one week and Thea felt bad for him so she wanted him to hang out with the group. Riley wasn't trusting of him. Ridge would actually cost Thea a match after getting the crew tossed out after being caught with a chair Jazmyn Nyx tried to bring in vs Jacy. This made Riley want a match with Ridge the next week which Ridge won. Riley wasn't happy Ridge was hanging around after that.
A few weeks go by of Ridge hanging around at ringside and he was either helping Chase U win with purposeful cheating or by happy accidents. Riley finally calmed down and accepted him. They officially made him part of the group by giving him a Chase U shirt. Duke secretly mistrusts Ridge after Ridge helped him win a match vs the OC by cheating. Helped Duke on a school boy to gain leverage behind the refs back. So they got this story where Ridge is a cheater basically and now Duke isn't trusting him because Duke doesn't want to win that way.
That's the basics of it. If you really want more I'm sure you can search "Chase U" on YouTube over the last month or so.
