Series creator Shonda Rhimes knew she'd be defending her choices. "When I pitched this finale at the beginning of Season 6 (those of you who know me, know that I pitch the end of the season first and we work towards it), when I pitched a gunman shooting up the hospital, it seemed fine," Rhimes wrote on the "Grey's Anatomy" blog. "Really it did. And then 20 or so episodes later, I started to write it and it did not seem fine. It did not seem fine at all. On an almost daily basis, I would come into work and throw myself down on the sofa in the middle of the office and burst into tears."
