I don't have a full blown theory, but a few observations:
Obviously the color red is quite prominent in some key scenes all through s7. Such as the key females in the episodes wearing the color red.
The color red also appears prominently in a scene with objects when heller is dealing with misdirection from Jane.
Also the return of Janes cup I think has more to do with a connection to the RJ case than we think, how did Lisbon get it back, weren't all the members of the CBI escorted off premises at the same time? If so why/how could she return to retrieve it?
Theory
From the RJ revel episode at the very end, the last shot there is a pull away, zoom out of the play ground and a playset with a picnic table, a guy sitting there with his back to the camera, jeans and baseball hat and maybe sunglasses just sitting there. Why? Why was he in the middle of the screen, who was he watching? Didn't appear to have any connection to kids or anything else. My theory? I think that was either RJ or someone watching for him.
I think BP is RJ and Lisbon (knowingly) is a long con to draw RH out but Jane fell in love and is having second thoughts thus his move to with draw Lisbon from danger. An attempt on her life will be made a the end and Jane wil
Be there with Grigsby( who have been secretly investigating RH and the BA) for the wrapup.

Re: "the whites of his eyes"
Notice the over use of the color red in the family garage, yes red is popular with Italian cars and in high end tools and garages, but it is an aggressive color to use in abundance on screen. The chairs, boxes and other large items when introducing us to the ultimate bad guys who were behind the hands on killer.
This leads to the wrap up at the end of the episode. Abbotts speech went along way to point of the switcheroo to the 'bad guy' and how they were fooled. Abbott took joy in revealing how HE fooled them. I can't dictate verbatim, but it was too the effect "that sometimes you see what you want to see no matter how hard you look" whatever the wording it felt like a direct message to the RJ fans looking for a storyline return. That wrap up seemed out of place not only for Abbott but also in the show. I don't know if heller is playing with us or foreshadowing a great wrap up, honestly I think he is capable of either one.
I really want a RJ return, I thought it was an amazing story line, but I often wonder if heller is just telling us to let it go, I hope not.
