Obviously it worked, because Cristina is then in with the docs to meet the patient, Linda, who has been in a few times previously to have stuff removed from her heart. Teddy explains that this time they are removing both atria and that should remove the cancerous cells once and for all. Linda then sees Cristina and she and her husband both greet her warmly; Teddy realizes Cristina is confused and "reminds" her that she helped Burke on one of Linda's previous surgeries, and Cristina covers to act like she remembers this and greets them warmly. Of course this then leads to a mix-up because they recall that she was getting married last time they met, and there's awkwardness when she has to explain that she was supposed to marry Burke but didn't, and in fact married Dr. Hunt just the night before. It's a little creepy how invested Linda seemed to be in her ending up with Burke, and she's a little short when she tells Cristina that regardless, it's nice to see her again. Dear Lord, woman, this kind of thing happens all the time, and it wasn't like you were in just yesterday. I paused my DVR right here and got a pretty awesome freeze frame of Owen just looking completely terrified, which cracked me up, and Linda does sound at least sound a teensy bit nicer when she offers them congratulations.
Meanwhile, down in the pit, Callie tells Lexie and Meredith that they have multiple burn victims. After they all guess incorrectly what happened she tells them it was an act of God -- a single lightning strike that took out eight victims, all on the same flag football team. We pan around to see them all singed and moaning and as one guy is brought in having a seizure, Bailey notes, "God was in a mood today!"
April wonders for all of us watching how one strike could do this, so Mark explains that based on the burns, it probably his one person and conducted to all the rest. He then sees Lexie there so he tells her to assist with his patient, who has a ruptured eardrum. She's less than thrilled at the prospect but heads off, and once she's out of earshot Mark asks Callie, once someone is out of the "nuthouse"... what is the appropriate amount of time to wait to propose? Callie is flabbergasted and once she realizes he's serious, sputters that it's a long, long time.
