After watching Red Sails in the Sunset I believe the following people could be RJ:

- Minelli: 10%
- Brett Partridge: 20%
- Walter Mashburn: 30%
- Max Winter: 40%

I gave Minelli and Brett lower % because Lorelei could have said "How come after years of working with him...still not longlife friends..."
Max Winter is the highest: His wife was murdered years ago (could have been RJ's trigger); he knew Jane's pain; he is rich and works in real estate. RJ's MO's (possibly) seeing life after the loss of the closest person to you. Tod Johnson told Jane he (i.e., Jane) should understand...etc.
