History Heartwarming / Monster

* The guy with the five spoonfuls of sugar belongs here, too.

* Vardeman, Suk and Lunge meeting at [[spoiler:Grimmer's grave]]. Also doubles as a Tear Jerker, not least for the way the inspector brings along the beer they never got to have together.

** Later in the same arc, Johan takes it upon himself to present the evidence to Schubert that proves Karl is actually his long-lost son, reuniting the two of them. Even though Johan does this with the intention of [[spoiler:getting into Schubert's good graces so that he can be entrusted with running his financial affairs before subsequently having him assassinated and taking over his business empire]], it is shown that he could just as easily have tried pawning himself off as Schubert's son using the acquired evidence (which Schubert outright states he would have believed), but chose not to in favor of bringing Karl back together with his father.

--> '''Lunge:''' Dr. Tenma... [[spoiler:I'm sorry.]]

* Nina comes very close to [[spoiler:shooting herself in the head, but Tenma reaches her in time. He carefully pulls the gun away from her, holds her tightly in his arms, and delivers a [[TearJerker touching]] [[YouAreNotAlone speech]] about how much she means to him]].
* The couple introduced in the Ruhenheim episodes, Henning and Franka, holding each other near the end of the series. Considering how they always bickered, even when first introduced, and Franka's obsession with winning the lottery and blaming her husband for not having enough money, after [[spoiler: the Ruhenheim massacre is finally stopped and the police come]] their reconciliation is heartwarming. Seeing her husband go off in a hurry to find and get back her winning lottery ticket, Franka desperately calls after him: "Honey, it's okay! We don't need it. I am content to live this way, it's enough for me." Then they finally smile at each other through tears and embrace. Even the policeman that was asking them for [=IDs=] just smiles and walks off, saying they can show them to him later.

* Even after everything that Johan has done to her, Nina [[spoiler:genuinely forgiving Johan]] can be considered a heartwarming moment. The entire series, she's been hunting him down and set to kill him, but Nina actually finding it in her heart to [[spoiler:forgive Johan]] is heartwarming in itself.
** Likewise, even after everything that he and others have been put through by Johan, Tenma not only [[spoiler:saves his life for a second time with Nina's encouragement, but visits him in the hospital when he is in a coma and reassures him that his mother loved him very much (despite her past actions)]].

* Throughout the series, Nina has had momentary flashbacks of an unknown, menacing-looking man (implied to be one of the people who experimented on her and her brother) reaching for her and saying, "People can become anything." [[spoiler: Towards the end of the series, it's revealed that this was Franz Bonaparta, having a change of heart and letting Young!Nina go free. He was reaching out to give her a comforting caress to the face.]]

** Likewise, even after everything that he has been put through by Johan, Tenma not only [[spoiler:saves his life for a second time with Nina's encouragement, but visits him in the hospital when he is in a coma and reassures him that his mother loved him very much (despite her past actions)]].

** Likewise, even after everything that he has been put through by Johan, Tenma not only [[spoiler:saves his life for a second time with Nina's encouragement, but visits him in the hospital when he is unconscious and reassures him that his mother loved him very much (despite her past actions)]].

** For context, she's a careless alcoholic for most of the series. Her changing her order from scotch to coffee marks the first step toward her recovery.
