Grey's Anatomy Season 7 Episode 4 Quotes

(to Meredith) You know this isn't normal.


Biology determines much of the way we live. From the moment we're born we know how to breathe and eat. As we grow older new instincts kick in. We become territorial. We learn to compete. We seek shelter. Most important of all, we reproduce. Sometimes biology can turn on us though. Yeah, biology sucks sometimes.
