A white person criticizing a black man from Baltimore for speaking in black vernacular- I see race in that. (And sorry if I've misperceived your ethnicity.) Remember that "wichu" is a common and acceptable way to combine "with you" that is yes, particular to black vernacular. Not trying to make this seem as a personal attack, I just see the criticism for Eric speaking in a very normal way to be confusing.
Honestly, I would be surprised if the winner isn't Bryan, though his edit is getting more unflattering right now. He does seem to speak using lines, and actual conversation. He doesn't seem like the worst, but I'm curious how Bryan would act around his guy friends back home, and whether they'd bro it up. He just seems a bit too faux polished. I'm also not convinced by Peter, which saddens me because I like Rachel so much!
