I'm fine with ANYONE else than Reede Smith. 

Reasons why Smith would make the worst RJ out of all suspects:

1. Too chubby

2. Appeared in 1 episode (before season 6) with no important, memorable appearance. Just a side character, the real FBI agent in the episode was his partner.

3. First appearance in season 5. This alone would make the reveal terrible.

4. Had barely even talked to Jane

5. He's already revealed to be bad and was shown killing Kirkland.

6. If he was RJ then no appearance before was RJ... I want The John from s2 finale to be the real one.
  
There are more reasons too. Hit the green button if you think Reede Smith is the worst suspect of em all. Hit the red button if he'd be a good RJ. 

I want to know what others think.
