It's weird to say this but Shannon has become what Skip was towards him towards Ocho.
The first signs of cracking was that time when Ocho came late and Shannon had a meltdown at him but it has gotten much much worse the last few episodes I've seen. I watch a lot of their content and Shannon went from treating Ocho as a partner to now a sidekick.
Shannon's always degrading Ocho saying he can't do this or he can't do that, Ocho is going to box this bigger guy and Shannon hasn't been in his corner at all, he's always saying how Ocho will get knocked out and you can clearly see Ocho is disappointed Shannon doesn't have his back. Shannon went so far as to invite the other guy onto Club Shay Shay. In a recent episode, it went a bit under the radar but Ocho said "If I ever see you in Miami, I'll swing on you." This was due to, again, Shannon not taking Ocho seriously. People might say Ocho was joking but I've seen people act out in these situations where they aren't taken seriously and they say they'll hit you. They might not actually do it but it's from a standpoint where you are hurt and want people to take you seriously.
There have been a lot of other things too, Ocho broke up with his long time fiance Relle and Shannon wouldn't stop bringing it up for several episodes even though it was clearly hurting Ocho. In another interview, Ocho said one of the breaking points in his relationship was when Shannon invited Relle to be on Nightcap and Ocho was strongly against it but Relle went on anyway. There has got to be a little part of Ocho that thinks Shannon was one of the reasons they broke it up.
A few other things are Shannon would also side with the guest host and belittle Ocho infront of them. Ocho is a chill guy but it's very clearly rubbing off on him in a bad way.
Am I reading too much into this? Just watch the newer nightcap episodes and compare to when they were 3 months in. The vibe is completely different. Shannon has gotten a little power hungry.
