The honeymoon girl is at the hospital for a nasty-looking rash on her leg. Cristina has drawn a line just above the rash; she tells the girl that if the rash doesn't cross the line in one hour, she'll get antibiotics and be fine. If it does cross the line, Alex explains, it would mean the infection's aggressive and they'll have to do a muscle biopsy. Honeymoon Girl, whose name is Claire, finds this unacceptable, as she and her new husband are supposed to run a 10K tomorrow. They are a power-outdoorsy-activities couple; they first noticed HG's rash when they were hiking up Mount Rainier the day before. Sydney overhears this as she's walking over, and is most impressed. "Wow, that's amaaaazing!" Cristina, trying to ignore this and be all business, asks if Claire fell or sustained any kind of trauma on the hike. Claire's husband Wade says she cut her foot on some oyster shells at the beach a few days ago. They were windsurfing in Puget Sound, obviously. Here's something funny about this storyline. Actually, it's not about the storyline, it's about me. I started a new job on Monday on the second floor of a big old building. Tuesday morning, I woke up to find that my legs were so sore I could barely stand up. They were sore, you see, FROM THE WALKING. Take that, Claire and Wade! Sydney giggles that they're going to need a honeymoon to recover from their honeymoon. Alex totally does the butt-kiss laugh, and it is awesome. Claire asks if she's going to be okay, and Alex says it's probably just a simple skin infection. Cristina says it's not, either, and points to Claire's leg. The infection has spread way over the line, and her leg is all puffy and angry-looking. Uh oh!
Mere runs into McDreamy and asks how the dog is. McDreamy says he's great, and they get to laughing about him. Before they can say much more, though, Addison comes over and marks her territory and ruins everything. "You should come visit! The dog, I mean." Mere's all, "Uh huh. Bye!" After she leaves, Addison tells McDreamy that she's looking for a neurosurgeon to consult on a fetal-spinal tumor. "You know anybody good?" McDreamy fakes a laugh, still having to pretend he likes his own wife.
Outside in the picket line, Olivia, Mean Nurse, and Hot Man Nurse corner George. They need him to go in and check on some of their patients. George is confused; how can he both picket and cross the picket line at the same time? Olivia says the patients are theirs, too, but they can't go in, so they need him to go in and do it for them. George doesn't know what to do, so he just stands there being a sad little union guy.
