Despite approximately 79 sneak previews giving away much of the plot, the Season 6 premiere of Grey's Anatomy still provided some plenty of dramatic high points.

Even though we knew the season-opener revolved around the death of Dr. George O'Malley, his colleagues went through the stages of grief uniquely and emotionally. 

Their respective story lines and personal struggles were neat to watch.

In this two-hour Grey's Anatomy event, 40 days passed in the Seattle Grace universe, 20 in each hour, picking up right where we left off in May. The episode titles set the stage, but there were plenty of developments and vintage Grey's Anatomy moments you never saw coming.
