I remember reading something that said it was a Jerome, but he was in the witness program for testify against someone who was a Jerome. Of course this was a rumor. So not sure how true this is.
Re: Sams Father!
I'm waiting to see Alexis' reaction when she sees Derek Wells, who arrives in PC on 30 July and will be played by William deVry. Perhaps Derek Wells is the name given to Jerome when he went into the witness protection program. I think the look on Alexis' face when she sees/meets Derek Wells will say it all, and we will finally know who Sam's father is.
