Thursday night's episode of GREY'S ANATOMY, written by Elizabeth R. Finch and directed by Zetna Fuentes, offered viewers a tale of two tumors-two very different patient cases in which the doctors want to try to remove a tumor but the patient (or patient's parents) do not want them to...for very different reasons. As the medical cases play out, we also get an update on the Arizona/Eliza romance, and the Meredith/Riggs romance (and Maggie's stance on it). We also see Edwards finally reach her boiling point with the existential crisis she has quietly having all season. Oh, and I'm pretty sure Alex is tracking down Jo's estranged, abusive husband...so that should be interesting.

The episode opens with Meredith lugging a giant portion of her bedroom wall-the one with Derek's drawing of a spinal tumor-down the hall to Amelia's room (PS where does Alex live now?). She offers the tumor to a very confused Amelia, who, along with Maggie is not sure why Meredith is choosing to do this at 3:30 in the morning. They later realize that it is because Meredith is considering inviting Nathan over and maybe doesn't want him in her bedroom if it is "a shrine to Derek". The sisters realize that Meredith and Nathan's relationship must be a big deal and decide to support it. Meredith initially cancels plans with Nathan, but by the end of the episode, after giving some advice to the suitor of a patient, she chooses to move forward. Now that this relationship is in full swing, I'm sure a huge wrench is about to be dropped into it.

The patients this week were very interesting. First there's Holly. She fell down a set of stairs after a steamy one-night stand. She also happens to have a giant inoperable heart tumor. She has seen many doctors and is resigned to the fact that she doesn't have very long to live. She has decided to spend her time hooking up with hot guys. Meredith, Aoril and Maggie are on her case, and Maggie thinks she can remove her tumor and finally convinces her to let her try. It turns out that Holly was right all along though and all Maggie can do is give her a bit more time by resecting parts of the tumor. It is Holly's story that allows Meredith to recognize that unlike Holly, she has a whole life to live-Derek left her behind and as she says to Holly (when she thinks that Maggie might be able to save her) the scariest thing to do is acknowledge that she has to live it. Meredith decides to take the leap and move forward with Riggs. Maggie and April decide that they want to take out of Holly's book and find themselves a hot hookup.
