I think with Ali's insecurities coming to a head when Frank leaves, it will be important to see which of the F2 lays out the ILY to Ali and when. She will need that assurance. In looking back at Jillian's season, Ed was the only one to tell Jill ILY prior to the FRC. In hindsight it was pretty obvious that Ed was the one she would choose. He was the only one to give her that reassurance she needed.
