I liked that he ended up with Izzie because I always believed they were meant to be. I never liked Jo or Jolex so I’m fine with Alex’s exit. What I have a problem with is why Jolex got married again this season? Why did the writers have Alex reassure Jo that he would never leave her? They must have had some inclination that Justin might leave this season and I’m sure he mentioned to them he was thinking of leaving, so bother having Jolex get remarried?
