Nah, Harry already had to kill Susan and he lost Murphy, I do not think JB is going to do that. I mean, Eleaine can die, of course, but not by Harry's hands. Also, much to my chagrin, I am beginning to suspect they are endgame. Jim deleted Susan and Murph and I do not believe Harry is going to love Lara unless he changes her so much that she is not a monster (in the moral sense) anymore. Which saddens me, because they are a great team.
I also do not think he is going to be with Molly, perfect as the couple is on paper, because he still sees her as a child. Unless...well, unless Harry remains the WK and Molly the WL, which I do not believe.
So who else? Sarissa may be an option, but I do not see it with good chances.
Of course, there is always Marcone, but I truly do not see Jim going that way
