That's so true I had enough izzie she doesn't survive the hall where Brooke Stadler was in and all that did she ever look food in the rubbish I don't think so....anyway I think Alex knows in his heart what he loves real is he propose 5 times lol
The personal growth of Alex was so good , then they had him just up and leave Jo like that for Izzie who ran out on him she managed 5 years with out Alex in their life . So tell him he could have been a dad and been with Jo she was better than Izzie
