1. Thank you, Ella, for asking the question that's been on all of our minds: what kind of doctor are you anyway?
2. Singing zombies = love. Cow in lab = no love. Cow COVERED IN POLKA DOTS in lab = seriously no love. Kill the cow, show! KILL THE COW!
I think, however, that we can all agree that Olivia needs to wear a fedora more often.
Also, did anyone else think that Olivia and Astrid-er-Esther were just totally about to do it or is my mind just incurably filthy?
