First of all let me say that I am not a Partridge fanboy. I always prefered the calm but overwhelming presence of Thomas or the "act" of "regular" Ray. 

But after reading some theories about Partridge was shown to us dead a second time and all the fuzz about Cho just checking the tattoo, I couldn't help but think that maybe Cho didn't chech the face because he knows that this guy isn't Partridge and he is an associate of his.

That is based on the fact that I'm guessing someone from the team will have connections to RJ. Thoughts?
