Sorry to disagree, but this must have been the worst filler ever - and I've seen them ALL. Just when I thought the series was getting better again after McDreamy, Mc Steamy, Lexie, Christina and Callie left. So far in season 13 I had been happy that the storyline was not drifting off to secondary characters but focused on Meredith, Miranda, Alex and Webber. I was hooked (something they've failed to accomplished in a long time) and was looking forward to another episode and wanted to follow the past weeks' developments - when they dropped this meaningless filler in between - so frustrating! This episode was not only implausible and boring, but interrupted the entire quality of season 13. Are the writers lacking ideas for the script? Maybe then it is time to call it before we get more disappointed. The characters have so much more potential, what a waste of time.
