Okay, readers, are you sitting down? DEREK'S HOUSE IS FINISHED. It only took five billion years. But it was kind of worth it -- the house is all windows and gorgeous views and wood and a gorgeous stone fireplace. Meredith lays it on a little too thick as she compliments his work; I mean, she obviously really loves it but she's also clearly trying to butter him up to stay. He tells her he can build her a house in Boston, and Mark can buy this one. "His dreams have always been my dreams." You mean, loving a Grey even when it seems difficult? Actually, Mark has historically done a better job of that than Derek as he flies off the handle and gets self-righteously indignant a lot less. After they have a laugh about Mark, Derek gets serious and tells her that Harvard is now offering him a 10 million dollar endowment and that he's going to use that to cure Alzheimer's which is his dream much more than the house. He then gently calls her on making the decision with Cristina. She says it's not the only factor and while she's serious, everyone knows she is a huge factor. Derek tells her that he's her husband, and she should make it with him. I hate having to give Derek any credit but I see his point. Though at the same time he seems to already have dismissed Mere's own opinions.
Bailey and Mere go back to talk to Jimmy about his worm, and Chloe both bitches at them for not seeming as concerned as they should about getting it out right away, and then at him for overreacting since she's not complaining and she's got a worm too. Jimmy yells at her that they know hers is in her arm but his could be anywhere and like any red-blooded man immediately panics that it might be in little Jimmy. Chloe tries to dismiss him and then it sinks in and she asks the doctors if that could happen. Before they can answer, he yells about his legs. His legs and arms have started going numb, and the doctors jump in to action. Chloe is totally worried while Jimmy melts down, and Bailey has Derek paged right away.
Derek looks at the scans and sees that Wormio Iglesias has gnawed through all of the discs in Jimmy's spine and is now nesting there, somewhere. He needs to operate immediately to try and get him out before he causes paralysis. Bailey immediately offers to assist and tells Derek, "I'm on your six." Yeah, I had no idea what she meant, just like Derek and Meredith, but as I have Google at my fingertips, I was able to look it up. She offers to get him prepped and tells them, "Lock and load, people." She suddenly landed in a Michael Bay movie. I expect armed men to run in at any time and start blowing things up... OH WAIT, that was a different season finale.
