History TearJerker / Fringe

* In The No-Brainer, Peter doesn't want Walter to meet the mother of Carla Warren, who died in a fire in Walter's lab, because he's afraid that Walter won't be able to handle it. Carla's mother asks Walter if there's anything she should know about her daughter, and Walter tells her that Carla had a beautiful smile and that he misses her.

* When Thomas Jerome Newton shows Walter a series of still images and asks what his strongest association with them is, four out of five of them draw an association with Peter: an image of Peter as a boy, a glass of orange juice, a bowl of custard, and a child-sized coffin.

* The Observer [[spoiler: August, who sacrificed himself for his human love.]]
* Walter's breakdown in "Snakehead".
** And again at the end when he sees that Astrid was hurt by the gang members.

* Walter's situation in the Amber Timeline. [[spoiler: The Peter we know drowned immediately after being brought to A-Side, which is why he's RetGone. Without him to help keep Walter anchored emotionally, Walter didn't receive the CharacterDevelopment of the past three years, and didn't leave his lab in all that time.]]

-->'''[[spoiler: Alternate Elizabeth]]:''' I forgive you, Walter. I forgave you a long time ago. And if I can, God can.

-->'''[[spoiler: Alternate Elizabeth]]:''' I forgive you, Walter. I forgave you a long time ago. And if I can , God can.

-->'''Walter:''' It's still possible-
-->'''Nina:''' *shouting* Oh Walter, anything is possible! [[spoiler: But the man I knew wouldn't try to destroy a universe! That doesn't sound like William.]]

* [[FunnyAneurysmMoment A call back to a previous, rather funny scene.]]

-->'''Walter:''' Please, son... whatever happens...don't let me go.
-->'''Peter:''' I won't, Dad. I promise.

* Both of Peter's dreams in Season 4. They start off as [[TastesLikeDiabetes ridiculously fluffy]] [[MoodWhiplash and then end]] [[YankTheDogsChain on a really awful note.]]

** Most notably Peter is protecting Walter from what he thins will likely be this woman blaming Walter for her daughters death. But when they finally do meet, all she wants is for Walter to share his memories of Carla with her, as he was the last one to see her alive, and she is desperate for even the smallest of moments he can share with her.

--> '''Alt-Astrid:''' My father... I cannot get the thought out of my mind. That I couldn't give him what he wanted because of... the way that I am. That he secretly wished that I could love him back in a way that he could understand. Do you think that if I were more like you, he would have loved me more? [[TheRainman If I was normal?]]

* Peter's situation in the Amber timeline. [[spoiler: He's brought back from being RetGone, but no one, including Walter and Olivia, remember him and Walter wants nothing to do with him because of his own guilt.]]

*** Walter's accompanying anguished scream of "I'm not losing my mind!" while cowering away. Even Broyles looks shaken at the state Walters in

* "Johari Window" tells the story of a the town named Edina whose people were badly deformed because of a military experiment with a pulse that hopefully will allow soldiers to become invisible but prolonged exposure caused physical deformities to occur to the people. One of the major people in the project was so consumed by guilt, whose wife and daughter were also affected by the experiment without his knowledge or consent, decided to built a machine that allows the inhabitants to appear normal without the deformities but the people would had to be confined into Edina to stay within range though he did gave the inhabitants a choice to stay to seem normal but confined to a specific area or leave so they can be free but have to deal with the deformities the rest of their lives. The townspeople choose to stay as they would rather have the illusion of appearing normal and forget then having to deal with the problems and did everything in their power to prevent people from finding out so they can live normal lives. The story moved the team so much that they plead and eventually succeeded in their attempt to protect the town and its people from intruding eyes.

*** On that note: it's hard not to get teary-eyed over the poetry of how the chaos of the entire series ends exactly how it began: [[spoiler: with Walter taking a little boy with him through a portal]].

* The BadFuture. The universe is breaking apart. The opening credits now include ''[[OhCrap water]]'' and ''hope''. [[spoiler: The other universe, with baby Henry, Henry the cabbie, Marilyn Dunham, Alternate Astrid, Christopher Broyles, Lincoln, Scarlie, Fauxlivia and all the characters we have come to care about, is already gone.]] Walternate [[spoiler: shoots Olivia.]] [[FutureBadass Ella]], who once fixed Walter's story, doesn't believe in happy endings anymore. [[HopeSpot But Walter has a plan.]] A really drastic plan.

** Peter mentioning offhandedly that Walter has become obbsessed with his his (Peter's) childhood recently, and has a habit of checking he's still breathing when asleep. On rewatch, this becomes absolutely heartbreaking [[spoiler: as you discover the original Peter died as a child. Walter is likely not only cultivating the memories of his Peter, but is also petrified of the idea that current Peter might die again]].

* When Peter [[spoiler:calls out Walter for kidnapping him from the alternate universe, says that Walter isn't his father, and then leaves.]]

* "She's me, only better." Oh, ''Liv''...
