Any one have any ideas on who the daddy is to CJ's daughter?? An unnamed character?? Or someone else we know??

I had a revelation last night thinking that it would have been pretty darn cool if before Saul left on his last mission with Michael & Victor - thinking it might have been his last time to say goodbye - he slept with CJ knowing she loved him....and because even though he truly loved Lizzie - he did really care for CJ.....and wanted her to know that???
