Tear Jerker Moments for Forever:
Episode 1, "Pilot"
- The look of intense pain on Henry's face after the train crash, only to see it worsen when he turns and sees that the crash has killed the pretty Russian blonde cellist he was chatting up is bad enough. Then the show reveals why he is drawn to women who look like that.
- Jo talking about her dead husband to Henry, especially after an earlier scene where one of her hookups saw his photo on her phone and she lied about who he was.
Episode 2, "Look Before You Leap"
- The parents of the victim, at the time believed to be a suicide jumper, visit the morgue to identify the body. Not normally allowing family and the like to see the body, nor being the one to help with the identification process (for obvious reasons), Henry does his best to console the bereaved parents of their loss. The victim's father asks if Henry had ever lost a child, to which he hasn't. For a moment it seems like Henry intended to use the loss of Abigail as a point of connection, and fails. Except that in 1945, when the pair first met, they also happen upon a healthy baby in a concentration camp during the war. Henry then raises the child as his own. This child is Abe, who is nearly seventy, inching closer to Henry's fear that Abe will eventually be gone forever.
Episode 3, "Fountain of Youth"
- Abe considered taking a de-aging drug he knew to have lethal side-effects because of how worried he was over Henry being alone after he died. He never took it, thankfully, but the sentiment is there, and Henry is deeply moved by Abe's sentiment when he confronts the latter about it later. However, it doesn't change the fact that this will happen eventually, especially considering that Abe is nearly seventy.
Episode 4, "The Art of Murder"
- As it turns out, the matriarch of the Carlyle family spent decades longing for her lost love (an artist) and became cold and bitter because of it. She arranged her own death so that the last thing she would see would be his greatest work, crawling into the exhibition hall after falling and breaking several bones while dying from poison.
Episode 7, "New York Kids"
- A flashback to the 1950s reveals that Henry abandoned his career as a doctor because he abandoned another man to die in order to protect his secret, feeling that he can't be trusted as a doctor if he can't put himself above his patients. He abandons his profession of over a century because of a moment of weakness, and it's suggested he's never truly forgiven himself for this act.
Episode 14, "Diamonds Are Forever"
- Jo rewinding and watching the tape of her late husband repeatedly, just so she can hear him calling her and telling her he loves her.
Episode 16: "Memories of Murder"
- Thanks to Henry's agelessness, after many years together Henry and Abigail find themselves unable to be a couple in public for fear of how they'll be seen. He tried to put off thinking about it, but you can tell Henry knew that it could only end a select few ways, and that that end would be soon.
Episode 17: "Social Engineering"
- A nurse, Henry's Love Interest, steps in front of him to shield him from Nora, who wants to shoot him in an attempt to show Henry's "gift" to the world, and gets shot by her instead. Hospital aides take Nora away, presumably to an asylum, and Henry is left in shock as he cradles her dying body.
Episode 18: "Dead Men Tell Long Tales"
- Henry spent two centuries believing he had failed in his attempt to free the slaves on his father's ship and that his immortality was a curse brought about, or deserved, by that failure. Fortunately, it turns out he was mistaken.
- Adam tells Henry that one of the worst aspects of being immortal is the sense of timelessness that develops. Now consciously thinking about the idea, Henry asks Abe when he repaired the clock on the mantel, which has begun ticking again, only to be told that it's always ticking, and that Abe winds it every day - Henry is already starting to lose himself to time.
- Additionally, while providing that knowledge, he also explains that he believes the gun he gave Henry is the one weapon that can kill him. Though he's been searching for a "cure", undoubtedly Henry has never truly had to decide whether or not, in the end, he should go on living; now he has a genuine chance, but would be abandoning Jo, Lucas, Hansen, and Reese, to name but a few, in the process.
Episode 19: "Punk is Dead"
- We finally get to see a bit of what happened when Abigail left Henry. He became absolutely distraught at the thought of her being missing and refused to believe that she could have walked away when the police explain to him that her last letter to him was actually a "Dear John" letter. He then proceeded to turn his living room into a Room Full of Crazy while trying to piece together clues before turning practically catatonic.
- Abe returns home to take care of his father and is heartbroken at the sight of Henry as a broken man. He has to resort to desperate measures and throw out all of Henry's work and unilaterally declare that the two of them have to move on even though it also pains him because he lost his mother.
- But, 30 years after Abigail left, we see that Abe hadn't thrown out Henry's Room Full of Crazy but actually moved it to a storage locker and had kept up the search for his mother while keeping it a secret from Henry because he knows that Henry is on the brink whenever the subject of Abigail is brought up.
Episode 20: "Best Foot Forward"
- Henry discovering his then-Love Interest Valerie dead in her studio from an overdose of heroin, which was something he had warned her about earlier in the episode.
Episode 21: "The Night in Question"
- Just about everything Henry learns about Abigail's final days is a mixture of this and Heartwarming Moments. She had realized that she didn't want to let her age stop her from living out her life with her family, and planned to write to Henry to tell him that. But before she could send the letter, she ran into Adam, and inadvertantly tipped her hand; believing he meant Henry harm and knowing he had no regard for the safety of bystanders, she ultimately gave her own life in service of a misunderstanding. Adam even tried to save her, but to no avail.
- Throughout the episode, the renewed grief from losing Abigail has Henry visibly on the edge of breaking down several times, especially when he has to oversee autopsies on what he believed to be Abigail's body not once but twice.
- Judge Graves' history. Leaving a man to what he believed to be his death after hitting him with his car, in fear of retribution upon Belinda from her jealous boyfriend; as far as he knew she chose never to speak to him again, and he ultimately became a judge in an attempt to atone.
