which passed from Olsen to Allen

Warning: Spoilers ahead for Teacup episodes 1-4!

Peacock's new Stephen King-endorsed horror TV series Carpet unfolded a mystery at breakneck speed, and introduced far more questions than answers by the end of episode 4. The basic premise of the show was established by the end of Carpet Episode 2, while Episodes 3 and 4 introduced several new players to the isolated farm setting, each with questionable intentions. Until now Carpet has built tension with distrust and paranoia, both due to the invisible threat beyond the blue line and due to the pre-existing relations between the neighbors trapped on the Chenoweth farm in Georgia.

Episode 3 and 4 of Carpet See Meryl and Nicholas become more familiar with the entity that inhabits Arlo's mind, known as "Harbinger" due to his constant warnings. Harbinger may have introduced a way for everyone trapped on the Chenoweth farm to cross the blue line safely, but the dangerous parameters leave plenty of reason for doubt. Meanwhile, a task force officer named Lieutenant Olsen entered the farm from across the blue line. While he claims to be an ally, Maggie's own misgivings and the masked man's warning not to trust anyone cast doubt on his intentions.

Who and what Lieutenant Olsen really is

The mysterious police officer reveals his true nature at the end of episode 4

As the trapped residents of the Chenoweth Farm do their best to unravel the mystery of the blue line, someone new drives to the farm. The man identifies himself as Lieutenant OlsenA Birmingham police officer who is at the farm on a mission that drives around and deals with what he describes as "situations" like those the Chenoweths and their neighbors find themselves in. Olsen is heavily armed and can cross the blue line without protection or mask, and as Valeria notes, he doesn't "look like a liar", much to Maggie's chagrin.

Maggie is skeptical of Olsen, who makes it clear that he is looking for Arlo because he came into contact with Mrs. Navarro in the woods. He also details the force beyond the blue line, which is a "concentrated vibration" that decimates complex organisms. While he claims to be there to help, Maggie is rightly suspicious, and baits Olsen into the hay loft of their barn, confronts him and knocks him out. while he is bound, Maggie and Valeria leave Allen with Olsen's gun to watch over himAnd he drinks her to come to him.

As she approaches, Olsen opens his mouth wide and something passes from Olsen to Ellen, just as it happened between Arlo and Mrs. Navarro in the woods. It is implied that although the entity sharing Arlo's mind, Harbinger, is benevolent, The entity that possessed Olsen and passed to Ellen Chenoweth is AssassinHarbinger's malicious opponent who is actively seeking to capture him as he goes from person to person.

What Arlo, Meryl and Nicholas discover in the woods

According to Harbinger, this may be the key to their survival

Harbinger/Arlo leads Meryl and Nicholas into the woods where they discover a strange crater surrounded by dead animals. It is there that Harbinger reveals his origin: he came from space, and is, in theory, an alien. This would explain his seemingly supernatural abilities, and why he speaks in disjointed English words - they are the only words he has learned to effectively get his point across. In the crater, the trio finds a puddle of strange rainbow-colored liquid, which Harbinger insists they put in a jar to take with them.

Harbinger reveals in episode 4 that they all need to drink the liquid to cross the blue line. However, he also noted that it is a type of poison, and drinking too much will also result in their death. The trio then encounters the masked man with the whiteboard, who requests the jar of liquid before crossing the line to take it himself. Nicholas stabs him in self-defense, and as Meryl tries to stop the bleeding, his face and name are revealed. His name is McNab, and He already knows Harbinger and is looking to help him.

What Ruben and Jacob found on the farm of the Navarros

Both men were apparently left in real danger

Reuben and Jacob travel to the farm of the Chenoweths' nearby neighbors, the Navarros. At the farm, they find a bloodbath with all members of the Navarro family dead by cruel circumstances, although not in the same brutal fashion as Claire Kelly, who crossed the blue line. As James investigates the house, He is pulled into the basement and captured by an unnamed man wearing a gas mask like McNabWho cares if Jacob was killed there and then.

It is clear that Carpet is echoing, if not directly paying homage to the plot of The thingJohn Carpenter's iconic 1982 sci-fi horror movie based on a 1938 novella by John W. Campbell, Jr. The two conflicting foreign entities in Carpet Are able to pass from person to person while maintaining the person's appearance, sow deep paranoia and distrust among an isolated group of acquaintances. That's almost a direct copy of the plot of The thingIn which a group of scientists, isolated on an Antarctic base, try to identify which of them has been replaced by an alien entity.

Finally, Ruben separates himself from Jacob to investigate the Navaros' grain silo, which is surrounded by their three dogs, who are barking at it. Inside, he discovers and is entranced by a glowing tree that radiates color and light. While no other information is given about the tree or its nature, its rainbow color indicates that It may actually be the source of the rainbow liquid that Harbinger claims will keep everyone on the farm safe of the dangers over the blue line.
