'''Season 2, Episode 20''':
!Brown Betty
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/300px-Episode220_3190.jpg]]
[-[[caption-width-right:300: I have spent my life making things that bring joy and happiness, to make the world a better place. Bubble Gum was one of my first. Ah. Flannel Pajamas. Oh, Rainbows. And my latest project, Singing Corpses.]]-]

Distraught over Peter's disappearance and attempting to console himself with a self-made marijuana blend (the titular Brown Betty), Walter gets roped into helping Astrid watch Olivia's niece Ella for a few hours. He tells Ella a noir-esque story about a woman with a broken heart searching for one that's been stolen, full of thinly-veiled [[{{Expy}} expies]] of people from Fringe Division and ultimately painting himself as a well-meaning man who nonetheless causes great pain and doesn't deserve Peter's forgiveness.

-->'''WALTER:''' Be careful, Stella (to Ella).
* AffectionateParody: Of FilmNoir
* AllAnimalsAreDogs:
-->'''WALTER:''' Gene, Gene, no licking. no licking.

* AmazingTechnicolorWildlife: Gene's polk-a-dots.
* AmericanAccents: Anna Torv seems to have a little trouble with Olivia's Noo Yawk accent.

* AnachronismStew
* ArtisticLicenseChemistry:
** Walter spells [=MnSO4=] as “manganese sulphate”, ignoring IUPAC guidelines, but later spells [=H2SO4=] as “sulfuric acid”
* ArtisticLicenseMedicine:
** The cricoarytenoid muscles do not actually contract the larynx. They are muscles intrinsic to the larynx. The posterior cricoarytenoid muscle laterally rotates the arytenoid cartilages, opening the vocal folds. The lateral cricoarytenoid muscle internally rotates the arytenoid cartilages, closing the vocal folds.
* TheBechdelTest: Passed.
* BigLippedAlligatorMoment: The singing corpses.
* BizarroEpisode
* CallBack: Picture of John Scott on Olivia's desk.

* HappilyEverAfter: With Ella's help.
* HeartTrauma
* LoveAtFirstSight:
-->'''RACHEL:''' We met only a few weeks ago, but... it was love at first sight.

** Instead of calling the Observer by a Month name, he is called by the Zodiac sign Gemini.
** The Observers are called Watchers.
* NoirEpisode

** We find out Walter's mother loved Creator/RaymondChandler and Creator/DashiellHammett.
** "How Can You Mend a Broken Heart" by Music/TheBeeGees

** The search for the glass heart seems to reference the Tin Woodman's quest in TheWonderfulWizardOfOz.
** The [[{{Chiaroscuro}} dramatic shadows]] during Creator/LeonardNimoy's appearance suggest he may have [[BeardOfEvil facial hair]] recalling MirrorUniverse [[TheSpock Spock]].

* StonersAreFunny:
-->'''ELLA:''' All you've done is eat all my snacks and talk about weird stuff and everything makes you laugh.
* StorybookEpisode
* TitleDrop:
-->'''WALTER:''' I'd hardly classify what I've just smoked as marijuana. It's -- it's a hybrid. Of Chronic Supernova and Afghani Kush. I call it Brown Betty.
* ThatRemindsMeOfASong:
** Walter sings Tears for Fears "Head over Heels".
** Broyle's does a very good job singing Traffic's "The Low Spark of High Heeled Boys".
** The corpses sing "Candy Man".
** Astrid really brings it with "I hope I get it" from Theatre/AChorusLine.
** Olivia sings StevieWonder's "For Once in my Life".
