As Bailey, Mere and Owen work on Naomi, Bailey prattles on about the insanity of keeping a lion and eventually notices that no one seems to be listening. She finally asks if she has offended them, in an effort to get one of them talking, but that doesn't really work until Owen mentions that Cristina doesn't believe in pets. Well, I'm glad he's clear about her view on pets since he seems to still not be as sure about her views on children. Mere mumbles, "Cristina doesn't believe in a lot of things." It's very pointed, and Bailey realizes that she's missing something and just drawls, "Ooooookay then."

Once Alex and Teddy have done the angioplasty there is more bad news: Martin had another heart attack during the procedure and needs surgery right away. Emma is incredibly nervous about it and Martin very sweetly apologizes to her for ruining their vacation. She assures him that he didn't mess anything up and in fact, they came face-to-face with a lion, which is amazing enough for her. She wishes him happy anniversary but he tells her to say that to him again tomorrow. Teddy is having a bit of a hard time with this whole display of love and it looks like it's work to keep the smile on her face.

As Derek talks to Lexie some more about the procedure she wrings her hands, and he finally demands to know what's wrong. She blurts out that she knows they don't talk about this kind of stuff, but what if she misses a great opportunity to get some help from her big brother? Huh. While that is technically now true, I didn't really think they were at the point of fully embracing each other like that, but I also think Lexie is trying to use anything that might help her get anything out of him. She asks, what if Mark is her soulmate? Derek quickly backs me up and tells her that he's neither her friend nor her brother right now but rather her boss, and she needs to buckle down. She immediately apologizes, and he tells her that she has an aneurysm to clip.

Cristina now has a tableful of Petri dishes each containing a tiny heart, and she's dripping stuff carefully into each when Jackson and Alex noisily burst in. Alex's pager is still blowing up and Jackson wants him to answer, but when Alex explains that he's trying to be cold and dead toward Morgan but it's only making her bug him more, Jackson tries to support his efforts. He jokes about how great Alex is at being a douche, so he can do this too. He uses Cristina as a great cold and dead role model -- all the while, she is ignoring them and thereby proves to Jackson just how good she is. Lexie then runs in and wants to talk about the lion, but by "lion" I mean "herself" as she tries to force a horrible metaphor between the surely lonely lion lady's life and her own. It's so awkward that I refuse to even try to transcribe any of it here. Basically, the guys think she is nuts. Cristina finally reaches her limit, and orders everyone out.
