Backed into a corner when Rita starts considering things Paul told her about Dexter before his death,Dexter covers it up in a hurried panic by saying he has a drug addiction.

6"There’s Something About Harry"
Season 2, Episode 10

But he can’t let him go either, because that would undoubtedly lead to Dexter’s downfall.It’s the first time viewers see Dexter’s internal turmoilabout a potential victim who just so happens to be someone he knows, respects, and can’t kill.

5"Hungry Man"
Season 4, Episode 9
Up until this point, Arthur Mitchell (John Lithgow), a.k.a. The Trinity Killer, one of thebest-ever single-season TV villains, seemed to have his family life together.

It’s also the episode when Debra (Jennifer Carpenter) starts to suspect Christine (Courtney Ford), and the young reporter’s parentage is officially revealed. It’s arguably one of the best episodes of not just Season 4, but of the entire series.
4"Lost Boys"
Season 4, Episode 10
The backdrop is an amusement park in part of this episode when Dexter realizes that they have misnamed Trinity Killer: he kills in fours, not threes, and each sequence begins with a young boy. Given his affinity for protecting children, Dexter is determined not to let this happen again. The hunt begins, and when Arthur gets away, the scenes with him and the now abducted Scott (Jake Short) are bone-chilling.
While the interrogation of Christine is happening, indicating that Debra is getting closer to the truth, Dexter manages to find Arthur, save the young boy in the nick of time, and solidify his confusing status as both a killer and a hero. It’s one of the episodes that really makes viewers wonder if Dexter is really a bad guy or not.
3“Hello, Dexter Morgan”
Season 4, Episode 11
One of the most talked-about andbest-ranked episodes of the series, “Hello, Dexter Morgan” is beautifully shot.

Meanwhile,Debra and Angel (David Zayas) finally learn that Christine is Arthur’s daughter, but she dies by suicide via gunshot to the head, right in front of Debra, in one of the show’s most disturbing scenes. It’s one of the best episodes to re-watch of the entire series.
2"The Getaway"
Season 4, Episode 12
There’s no question that this episode is the most emotionally charged of the series, withthe most disturbing deathas well. The walls close in for both Dexter and Arthur. Dexter finally gets the man he once admired on his table, and they exchange profound words about life and the inevitability of any serial killer like them having to choose their urges above all else.Dexter insists he’s nothing like Arthur, and hecanhave it all, an idea that Arthur knowingly laughs at.
There’s a reason he does this. It’s in this episode that Dexter realizes death will always follow him. He can’t have it all and continue to be the person he is at the same time. The lesson is learned in the most tragic waywhen Dexter arrives home to discover that his entire life has been turned upside down. The build-up to this moment is as heightened as they come, especially with an ending no one could have suspected.
1"The Big One"
Season 5, Episode 12
Throughout the entire series up to this date, Debra had never been so close to catching her brother in the act than in this episode. While Dexter tracks Lumen (Julia Stiles) to the abandoned summer camp where Jordan Chase (Jonny Lee Miller) is keeping her captive, Debra has figured out the location as well.She literally comes face to face with Dexter and Lumen red-handed, except there’s a sheet between them so she can only see their outlines. Rightfully believing that the mysterious people are Jordan’s last victim who escaped and her vigilante friend (based on a prior theory), Debra makes the difficult decision to pretend she never saw them and warns them to run before she calls for back-up.
Debra makes the difficult decision to pretend she never saw them…
Beyond this scene-stealing moment,the season finale episode sees Dexter question if he truly is a monster after all, now that he has met someone inherently good who accepts him for who he is. When Lumen decides to leave, however, feeling satisfied and like she no longer needs to kill, he realizes he’s a lone wolf once again, and probably always will be. There are so many layers beneath the surface of this game-changing episode, including a demonstration that maybe Dexter does have some capacity for emotion and love.
