In that scene Deny dies. Izzie lies next to him and no one was able to move her.
In that scene Izzie was holding on to whatever left of her dream. Deny was dead but she sticked to him as if her life depended on it. Everyone who tried to move her failed, except for Alex.
Alex stepped in, stood up to her and finally carried her off the dead dream.
Only in a perfect world, a man will love a woman so much that he will step in and lift her off a pile of dead dreams.
