The second episode of The War Between the Land and the Sea dramatically escalated tensions between humanity and the Homo Aqua. Titled Plastic Apocalypse, it saw Barclay thrust into the heart of high-stakes diplomacy, culminating in a shocking global event. As the episode concluded, humanity was left reeling and facing a daunting new challenge from beneath the waves.
In the episode, Barclay struggles to follow a rigid diplomatic script while connecting with Salt, the Homo Aqua leader. When human promises for change fall short, Salt delivers a terrifying lesson by pulling all plastic from the world’s oceans and raining it down on human cities. The crisis forces a new, perilous negotiation term: the next meeting must be held deep in the Atlantic Ocean.
How Barclay Became the Unlikely Human Ambassador
The central twist of the series is the diplomatic role forced upon Barclay Pierre-Dupont, a low-level UNIT transportation arranger played by Russell Tovey. In the first episode, during a tense initial encounter with the emerged Homo Aqua, Barclay made a simple, respectful gesture over their dead. He made the sign of the cross. This act of kindness was noticed by Salt, portrayed by Gugu Mbatha-Raw.
Salt subsequently dismissed all seasoned human politicians and diplomats, insisting that Barclay alone be appointed as humanity’s ambassador for all negotiations. UNIT leader Kate Lethbridge-Stewart, played by Jemma Redgrave, had no choice but to agree to the demand. Barclay’s lack of political experience and perceived honesty made him the only acceptable human representative to the Homo Aqua, setting the stage for a deeply unbalanced and personal diplomatic process.
The Tense Negotiations and a Critical Off-Script Moment
With global tensions soaring, Barclay was prepped intensely by UNIT and world governments for his first official meeting. He was given a strict script and an earpiece to ensure he stayed on message. The negotiations took place at the Empress Hall, with a massive water tank emphasizing the presence of the aquatic species.
The session took a sharp turn when Salt requested a glass of water from the local river. When a murky, contaminated glass was presented, she asked Barclay to drink it. Knowing the water was poisonous, Barclay removed his earpiece and went off-script. He spoke directly to Salt, admitting human failure.
โBecause we were stupid,โ Barclay said. โThatโs the truth of itโฆ Weโre just sat at home, flicking through our phones, making tea, thinking itโs someone elseโs problem. But itโs not. This is my fault. We all played our part.โ
This raw honesty resonated with Salt, who later called him her “favorite human”. However, this moment of connection was fragile, built on Barclay’s personal empathy rather than official human policy.
Salt’s Ultimatum and the “Plastic Apocalypse”
The fragile diplomacy shattered during the next round of talks. Following Barclay’s off-script moment, he was pressured to adhere strictly to the prepared statements. He presented humanity’s official offer: a promise to reduce ocean pollution by 50 percent by the year 2065.
Salt rejected this decades-long timeline outright. She highlighted the immediate suffering of her people, asking if they should wait “while we choke on your plastic and sewage”. Manipulating the politicians’ own scripted language about a “greatest desire” to clean the oceans, Salt decided to grant that wish immediately.
Using the Homo Aqua’s mysterious abilities, possibly linked to a telepathic “oceanic mycelium” network, Salt and her people removed every piece of plastic from the world’s oceans and waterways. They then caused it to rain down on human cities across the globe. Streets were buried, people were killed by falling debris, and chaos erupted. As people cried out, Salt stated simply, “We are cleaning up your mess”.
Actor Alexander Devrient, who plays Colonel Christofer Ibrahim, commented on the powerful visual, saying the actors didn’t need to pretend to recoil from the simulated plastic waste. “It’s so nasty. Physically, you sort of recoil. It just goes to show how much we waste,” he said.
The War Begins: Salt’s Three Conditions for Peace
In the aftermath of the plastic rain, Barclay confronted Salt, accusing her of jeopardizing the diplomatic process. Salt responded that the war “was started a long time ago by the humans”. She then laid out three non-negotiable conditions for peace:
- Immediate cessation of all pollution in oceans and waterways.
- Formal designation of all oceans and waterways as Homo Aqua territory, with a ban on human transport across them.
- The next meeting must be held below the Atlantic Ocean, at a specific deep-sea location, to prove human commitment to equality.
The third condition sent a shock through the human delegation. Salt provided coordinates in the Romanche Fracture Zone, an abyss north of the Equator off the coast of West Africa. Kate Lethbridge-Stewart immediately recognized the danger, noting, “Manned submersibles have imploded in less than half that” depth. To prove their commitment to peace, humanity must now venture into the deepest, most hostile part of the Homo Aqua’s world.
