[spoiler:2zv9pla2]I am not going to be popular with Cait but I think it was time for both characters to leave. George was barely a thought in most episodes, and he would be wearing a red uniform if he was on the original Star Trek. :laugh4:
Izzie's thing with Denny was just icky...couldn't they have figured out something better? I adored Denny and found they cheapened him big time. :undecided:
I think her death also was necessary for Alex's emotional development...boy did I cry when he did. :sad3: Just like Lost's Sawyer losing his grip on Juliet and being devastated.
I think that Katherine Heigl needs to get some serious roles in movies (no more fluff roles like Knocked Up, 6 million Dresses, etc) and she could really spread her wings. IF she stayed with Grey's she might've gotten pigeon-holed as an actress and that is a real danger. I wish them both well in their future endeavours.
