To be honest, I felt like Young was just kind of the guy who got caught. With that said, out of all the Nexus members, it's my opinion at least that Darren Young is the weakest link. I'm sure there could be some subtlety in there with the "Black John Cena" reference pointed out a few weeks prior, but in this case, it was just the guy who got caught.
On a side note, if there really was marketability to the "Black John Cena" thing, it would have been wise, and amusing, to debut Young as "Juwan Seena" or something. Have him with the same haircut, similar attire, etc. Would have made for great comedy, but the dude would have been dead on arrival as there's absolutely nowhere else to go with a gimmick like that. It would have been Gillberg, but darker.
Lucky for Young, he's involved in a greater storyline, one that will get more out of him than anything else ever will I predict. I would advise no one to look deeper into this than need be. Young won't be out of the group, nor will he face consequences for getting beat up. He got caught when Nexus was outnumbered and he took a beating, simple as that. If you are Nexus, why let your group continue to dwindle in number. It is the sheer numbers game and interchangeable parts that have gotten them this far, hasn't it?
