History TearJerker / InfinityTrain

* Hazel’s decision to leave Grace and Simon in order to travel with Amelia instead, which leaves Grace absolutely crushed. Making things worse is the plucky six-year-old doesn’t even wave or smile as she says goodbye.

** It was very hard to watch Grace break down as Hazel departs. She had grow to care for Hazel over their journey as a sister/mother to the vulnerable Hazel, and was ready to live with Hazel in the Apex. However in the end the plucky girl shuts herself away from her. Hazel doesn't even depart with a hug or a smile. Hazel only offers grace a matter-of-fact "Good luck" before leaving. Completely heartbroken, Grace continues to sob as she and Simon make their way into the next car.

* Grace being tormented By the image of Hazel blaming her for everything that's happened; trying to control everyone around her, Tuba's death, and worse of all desperately keeping up the act in the previous episode to protect herself. The memories and accusations overwhelm Grace with despair, a far cry from the headstrong cult leader she was at the beginning of the book.

* Grace ends up saving's Simon's life and he repays her by knocking her off. He soon starts to cry, possibly realizing he killed his best friend for years before completely snapping and starts laughing mad as his face is glowing with all those numbers. Even the Apex children are shocked that Simon would do such a thing.

* The ending. Grace is completely alone after losing her friend, little sister figure and Tuba. All she can do is admit to the Apex that what she did was wrong and they had to change things for the better. As the kids start talking about the adventures ahed, Grace can only give a melancholy smile while a little bird perches on her shoulder.

** On Simon's side, we see what happened with him and the Cat, and Simon is clearly ''devastated'' when she abandons him in her panic, and only survives because of Grace. We also learn that Simon's number when Grace saved him was at 55. If he had known that his number was supposed to go down, he would've been able to leave sooner. Grace's lie about numbers = strength deeply affected him, and in the end, [[ForWantOfANail this ''one'' lie]] (as well as Simon’s refusal to accept the truth) ended up killing him.

--> '''Grace:''' It's true. I'm afraid. Afraid of being wrong, of disappointing others, of not being enough. I did everything to avoid being alone... and that's exactly how I ended up.

* Grace ends up saving's Simon's life and he repays her by knocking her off. He soon starts to cry, possibly realizing he killed his best friend for years before completely snapping and starts laughing mad as his face is glowing with all those numbers.

* Simon's death. He did terrible things while on the train, but had enough sense of mind to be conflicted abouthis actions, even as he almost kills Grace. Throughout the book, we see that he was a scared little boy who was abandoned by the Cat and almost killed by a Ghom and in the end, he's unable to let go of his trauma and hurt. His choices, despite the guilt he felt, ultimately led to his death. The Train means business - only personal growth can save you and help you survive.

** The Cat, on her part, looks back as Simon leaves with pity, knowing that Simon will regret going through Grace's memories, and can't stop him. She's right.

** Even if Hazel isn't in any immediate danger with Amelia, the latter is still very aloof and has yet to see Hazel as anything more than potential research material. When Amelia makes it clear that she isn't going to waste time being Hazel's caretaker, Hazel says that Grace and Simon weren't much better and that she will take care of herself from now on. Hazel's journey with the two left some ''deep'' scars.

-->'''Amelia:''' Don't you get it?! [[PleaseDontLeaveMe I don't]] ''[[PleaseDontLeaveMe want]]'' [[PleaseDontLeaveMe a life]] [[TheLostLenore without Alrick]]!!!

* Let's put it this way. '''Everything'''.
** Hazel in denial about Tuba being wheeled, wanting her back and promising that she'll be good from now on if it means she'll be with Tuba again. That's not how it works...

--->'''Hazel:''' I'm afraid of the wheel!
** Hazel wanting a funeral for Tuba, and Simon refusing it because there's no body. Grace is at this point really upset at Simon's callousness, especially when Hazel blows up and explains that it's all Simon's fault that Tuba is dead.

** Hazel singing the full version of Tuba's lullaby and then learning to move on from Tuba's death. [[SincerityMode Really, get those tissues.]] In this, there is absolutely no background music, so we only hear Isabela Abelina (Hazel's VA) singing.
* Simon continues to his escalating insensitivity and apathy problems by telling how Hazel was a ''brave'' girl, that she'll be able to be with other ''passengers'' and even write her as a character in his novel. You can tell that Hazel hates him.

-->'''Hazel:''' ''(on the verge of crying)'' I'll be Tuba now! ''I'm Tuba...''

** The Cat, on her part, looks back as Simon leaves with pity, knowing that Simon will regret going through Grace's memories, and can't stop him.

'''Simon:''' But you didn't come back for me.

* The cars that Amelia made, like The Unfinished Car, are all being "quarantined", regardless of any passengers or denizens inside. Even worse, Hazel just being ''inside'' a car when it's scanned will have the same result, meaning that Hazel is indirectly responsible for what happened to Tuba; even if Simon was the one who actually killed her, he would never have had the chance if the cars hadn't shifted.

*** Just before Tuba tosses Hazel to Grace, Tuba sings their "Don't worry" song. That's the last thing she ever says...

** Hazel singing the full version of Tuba's lullaby and then learning to move on from Tuba's death. [[SincerityMode Really, get those tissues.]]

** Hazel and Grace climb up a tree with Hazel thinking that Tuba would love to see the sun. Instead of a body, Hazel uses the rock inside Tuba's satchel as a makeshift corpse before she begins her eulogy. When Hazel asks Grace to chime in, Grace slowly reveals that she liked Tuba as the tears form in her eyes as the horrors of what she's committed for years hits her like a train.

* We learn as to what happened with The Cat and Simon. The Cat panicked and didn't even realize Simon was gone until she went into the next car and found him missing. However, when Simon points out that she never came back for him, she admits that she did him wrong.

-->'''Hazel:''' "I'm afraid of the wheel!"

** Hazel wanting Tuba back and promising that she'll be good from now on if it means she'll be with Tuba. That's not how it works...
** Hazel seeing that she's a train person and asks if Grace hates her. Then she panics, afraid that Simon is going to wheel her. It's at that moment Grace realizes just how horrible she's been in the past.

[[AC: The Canyon of the Winged Golden Snakes Car]]
* Hazel really hates Simon getting in Grace's personal business. She starts throwing rocks onto the ground in disgust and doesn't care that she's turning into a turtle, stating that she'll use her turtle form to protect her and Grace.

-->'''The Cat:''' I didn't leave you, Simon. I ran...there's a difference.
