History Fridge / GreysAnatomy

** Callie thinks that Owen is Skyping with a MAN named Teddy. Hooray for ColorblindCasting and GenderNeutralWriting.

* Fridge Brilliance for Callie being revealed to be such a good singer and named after the Greek goddess literally called "girl with the beautiful voice" (Calliope). What makes it meta? This was no accident: the part of Callie was written for Sara Ramirez after she won her Tony award, getting named that is a bit of an in joke and makes a damn lot of sense.

* Owen did not break off his engagement with Beth until after the decimating ambush on his unit; presumably he also first appeared on the show and kissed Cristina ''before'' that ambush. That makes him a ''three''-time offender of YourCheatingHeart. Yikes.

* When they first meet, Maggie Pierce can’t remember Jo Wilson’s name, despite never messing up anyone else’s name because [[spoiler: Jo Wilson isn’t her real name.]]

* The revelation of [[spoiler: Amelia having a massive brain tumor]] explains a lot of her rather erratic behavior over the course of the series. Indeed, when brought in to consult, a mentor openly tells [[spoiler: Amelia that this tumor didn't just spring up but has been compromising her impulse control and decision making for some time. "You are not of sound mind now and you haven't been for years.]] Thus, so much of Amelia's actions and personality that seemed wild are explained as [[spoiler: caused by the tumor.]]

** I don't know what your metric for faring much better is, but her reaction to [[spoiler: Owen getting shot]] could not have been worse. She basically went on a downward spiral of PTSD from that day and ended up quitting her job. Granted, [[spoiler:Owen being shot right in front of her] was only one part of the reason she had PTSD from that day, but it was a fairly large part.

* Owen did not break off his engagement with Beth until after the decimating ambush on his unit; presumably he also first appeared on the show and kissed Cristina ''before'' that ambush. That makes him a ''three''-time offender of YourCheatingHeart (depending on your definition of "cheating", of course). Yikes.

* Amelia is seen to be on edge when April and Jackson's [[spoiler: baby turns out to have an illness meaning he'll die a few minutes after birth]]. Why? In Private Practice she had a similarly painful storyline and is reliving the experience. As she tells Owen at the end: [[spoiler "My baby lived for 43 minutes"]]

* FridgeBrilliance: Christina being unable to deal with Burke being shot makes a lot more sense after we learn that her father died in a car accident right in front of her when she was nine. However, she manages to overcome this, and [[spoiler: fares much better when Owen is shot]].

** Why would Karev date Meredith and act like a good guy despite his backstory ? Because he knows that Meredith is the chief's daughter and could get favor by taking her lastname.

* FridgeHorror: "You have apple hair. I threw a pancake in the river! The River!" It seems funny at first. Until it's not.

* FridgeBrilliance: Christina being unable to deal with Burke being shot makes a lot more sense after we learn that her father died in a car accident right in front of her when she nine. However, she manages to overcome this, and [[spoiler: fares much better when Owen is shot]].

** Charlie [[spoiler:who had be previously shot]] says at one point [[spoiler:"Shoot me!"]]

** Karev says "I always say never mess with the crazy chicks," which is ironic because he was involved with Rebecca [[spoiler:who went crazy and had to be committed]] and right after, he says "she's probably gonna go full-on Izzy," referring to the only other serious relationship he ever had on the show.

** Bailey in braids, a call back to an earlier episode where she was shown as a meek intern known as Mandy wearing dreads.

* During the flashback to Bailey's intern years, her inept (and bitchy) resident ends up incorrectly diagnosing a woman and removing her gall bladder and ovaries, among other things. After Bailey correctly diagnoses the woman with a relatively simple to treat illness, the resident is not seen in any other episodes. [[FridgeBrilliance This troper smells a lawsuit...]]
