History Series / TheBarrier

** The old man who attempted to kidnap Sergio earlier in the episode shows up at the Mújica-Noval's appartment, this time with a middle-aged couple in tow. They ask to be allowed into the apparement, they are refused for obvious reasons. The woman makes a plea that gives the scene a whole new spin:

* NewChildLeftBehind: Part of people's motivation to make sure [[spoiler:Clara]] is taken to a safe place comes from the fact that they either knew her unborn son's father or at the very least approved of what he did before getting killed.

** After disappointing Emilia and Hugo by [[spoiler:refusing to give Marta back after Alma has her abducted a second time]], Luis is makes a speech on live television that is intended to help Alma and the President further their plans to [[spoiler:get more children to use as noravirus antibody producers]]. Due to Alma monitoring how things look onscreen from another room and Iván resting, Daniela is the only member of the family in Luis' office during the speech, seemingly reluctantly due to being angry at him from a previous discussion. During the speech, Luis gives Daniela a quick glance, to which she responds by walking to a touchscreen and doing a manipulation on it that locks the only door Luis' office shares with the rest of the house. This indicates both that Daniela was intended to be in the room during the speech all along and that Luis is going to do something at least one person present in the house isn't going to agree with.

* WouldHurtAChild: Different degrees of this exist, ranging from Alma and Alejo's "would let multiple children die for science" to the President's "would [[spoiler:order a bunch of children to be killed because their existence inconveniences me]]".

* SecondLove: Luis and Emilia both genuinely love the partners with whom they had children, but their past relationship with each other is heavily implied to have been very meaningful for both of them. Luis is shown to not be completely over the day Emilia told him she was going to marry Ramón twenty-five years later, while Emilia's response to a visit from him is to start preparing a dish she used to make for him, minus the meat that has become scarce.

* RebelLeader: Whil Jorge and Iris are the leaders of the pre-existing LaResistance. By the end of the series, [[spoiler:Luis]] ends up being presented as this trope in the media and being considered this by many due to being the person who tells the public about the government's most nefarious plan, [[spoiler:already being a known face to the parents of missing children,]] and getting the support of many law enforcers.

** How Emilia was let into Sector 1 in the penultimate episode, especially without anyone in the Covarrubias household knowing in advance, at a point where security was ''tighter'' than usual, is never addressed. Any previous occurrence of Hugo and Julia going in or out with someone else, barring a case of a conveniently timed noravirus patient in the line, has required calling someone from the Covarrubias household to sort the situation out.

* PistolWhipping: Alejo uses his gun to hit Julia at a point where he has her at his mercy.

** Pedro gets very loud slap from the nurse caring for him for breaking the rules interacting with his father. His father is leaving the scene and can't turn back without getting into more trouble, but close enough to hear the incident. He's clearly made uneasy by the fact that interacting with his son resulted in him getting hit by one of his wardens.

* {{Lockdown}}: When worrying news about the noravirus epidemic is announced, Julia mentions the risk of Madrid going into lockdown in response, which would cause supply problems.

** Emilia knocks on [[spoiler:the nurse's]] door right when she's pointing a gun at Álex with the intent to kill him.

** In the finale, there is a standoff at the checkpoint between sectors between a police detachment that has been ordered to shoot anyone trying to go through the checkpoint and a crowd mostly made of Sector 2 inhabitants whose main revendications is to have the children detained for Alma's reasearch given back to their families. Meanwhile, it just so happens that another set of characters has freed the children. The leader of the police detachment gives the crowd a few seconds to disperse before shooting starts and starts a countdown, which he almost finishes before getting interrupted by a greeting from the fastest runner among the children. Whose parents happen to be close enough to the front of the crowd for them to see each other, to boot.

** The policeman lieutenant guarding the checkpoint between Sector 1 and Sector 2 in the finale is ordered to have anyone trying to go trough it shot down. When asked to please not shoot the crowd that shows up asking for the detained children to be given back to their families, the lieutenant says his orders are to shoot.

** Alma at some point quips that she'll go down in history in a role more important than Luis'.

** In a combination of two of the previous cases of the trope, Alma finds out about the "Sara" masquerade when Alejo calls her about the chips and refers to Julia Marta's ''aunt''.

** Julia is shown to believe it's not ''that'' easy to catch noravirus. [[spoiler:She turns out to be functionally immune.]]

* ExactEavesdropping: Enrique drops by Fernando's office and says he wants him in his office in a couple minutes. On the way to his own office, Enrique is met by [[spoiler:one of the nurses watching the detained children, who has come to tell him about "one of his men" approaching the children without permission]]. The short notice given by Enrique, combined with a convenient angle in the hallway, allows Fernando to hear most of the conversation without being seen by either participant and figure out that his best option is to ditch the meeting with Enrique and not stay in the building much longer.

* EmpathicEnvironment: A storm starts right around the time the rebels get into Sector 1 and start marching towards the President's residence.

** Alejo finds Hugo alone in a location where he is known to have come with Julia and holds him at gunpoint. When Julia reappears, it's to bring a blade in close proximity to Alejo's neck from behind an make him drop his gun.

** The fact that this is ''not'' the case for many of the children detained for Alma's research eventually becomes a plot point. In addition to this, when she eventually tells Luis about them and tries to claim they are mostly orphans for whom she's provinding, Luis promptly asks about [[spoiler:Sergio, whose biological parents were killed soon after they found him again]].

** Alicia had a really hard time convincing those around her that she had seen her officially dead son at the registry.

** The footage of Alejo's camp that Julia finds Marta and Sergio watching allow her to recognize the place when she and Hugo wind up in it.
** Luis asks for the ambulance that was used to [[spoiler:bring a sick Iván from Alejo's camp]] to be parked behind the house so neighbors won't see it. It's later used to [[spoiler:smuggle Luis out of Sector 1 after he uses the speech to alert people of the government's true intentions towards their children]].

** Hugo has the keys of a working car at his disposal on the same day that Julia finds both the CIM's location and a clue that Marta is detained in it. While Hugo tries to leave the Covarrubias property under the pretense of test driving the car after repairing it with Julia hiding in the back seat, Rosa asks to be driven to the store alongside Manuela, something that will have trouble happening without Julia's presence being discovered. Rosa suddenly realizes that she and Manuela are too busy to afford the time they would lose if the car broke down and changes her mind, before anyone else tries to get inside the car.

* AngryCollarGrab: When Enrique sees [[spoiler:Alejo]]'s corpse, he grabs a random policeman's collar while asking him to find the killer.

* AlmostLethalWeapons: The bullet [[spoiler:Luis]] injury gets in the finale merely requires him to cajole it for the rest of his screentime and allows him to still be alive in the epilogue. It's especially blatant because he was shot twice and the person who took the second bullet for him only had time of tearful farewell to their loved ones before dying.

** On top of everything else, there is the looming risk of noravirus. The way those sick with it or exposed with it are handled apparently has a bad enough reputation that people go to great lengths to hide it.
