Invasion (Season 2) Episode 4 “The Tunnel” Recap:
In the second episode of Invasion season 2, we saw Jamila (India Brown) deciding to leave her home in search of Caspar (Billy Barratt). She became increasingly restless because of the lack of answers about his whereabouts. Besides, her recent dreams made her believe that he is calling out for her. While on her path, she teams up with Caspar’s old friends – Alfie (Cache Vandepuye) and Darwin (Louis Toghill). They seek Monty’s (Paddy Holland) help to go to Paris. They were not on the best terms since Monty used to bully their group. Still, his sister Penny (Ruby Siddle) convinced him to drive to Paris to find Caspar.
Journey to Paris
Now, the fourth episode begins right around the time the president decided to attempt a coordinated response against the aliens, who had held them hostage for a long time. Monty drives his past classmates from the UK to a building in Paris, where Caspar supposedly is. They engage in a playful banter about a song in Monty’s playlist – Kiss from a Rose. It embarrasses him that they found it. Eventually, he stops the car after seeing a group of people stopped by the army personnel. Jamila learns that the borders to France are closed. They turn on the radio to realize the global plan to retaliate against the aliens.
The Tunnel
Hearing that, Jamila tells Monty to drive in the opposite direction and enter France through a tunnel. She is determined to find Caspar, which leads her to take this risk. Initially, Monty decides not to join for the sake of Penny’s safety. But he soon decides to go along after ensuring that Penny will follow all of his orders. The group enters the tunnel without the military noticing them. Suddenly, they notice something strange, like a blast. But Jamila convinces the group to stay put and show courage instead of going on living as they are otherwise. She believes finding Caspar can give them a fighting chance against the aliens.
Because of Jamila’s pep talk, the group agrees to walk through the tunnel to find Caspar. Penny goes on and on about tunnels and shares all the encyclopedic knowledge she has. Monty shuts her up. Then, he speaks with Jamila about Casper and how she understood his special power. Monty’s curiosity seems a bit strange, considering he was terrible to Caspar back in school. So, she wonders why he is tagging along with them. He hides his probable interest in her by saying he is doing it to save the planet. Then, they all notice some military men dead, lying on the floor.
The Transmission

Suddenly, Penny goes missing, and an alien approaches them. But it dies by itself before reaching them. They find Penny moments after that incident. She brings them to a crossway to notice a bunch of dead alien forms. Eventually, they notice a liquid surface that has ripples on it with a sound. Once Jamila and Penny keep some objects on it, the sound stops, and so does the movement. Jamila considers it their transmission. While trying to reach the other side, they come across several bodies lying on the floor. Suddenly, Penny starts feeling that the aliens are just around the corner. The group creates a barrier so that the aliens cannot reach them. Monty makes all the effort to calm Penny down in this stressful situation.
Casper’s Condition
Caspar has not recovered from his coma. While Dr. Gabriel does not have much hope for Caspar’s recovery, Dr. Esmee Gagneux (Emeline Lambert) considers it a case worth being optimistic about. Soon after, Gabriel shows her a video of alien species being killed. Despite that, a Malaysian kid in their facility senses a danger along the way. So, Esmee does not consider the death of aliens as a victory just then. Later, an ambulance driver gets killed on his way to the hospital. In his last moments, he tells Esmee that the aliens are coming. Esmee realizes that the aliens are not dying; they are returning even stronger.
The children from her entire ward start sensing their presence. Although she needs to go back to her duty at the hospital, she ensures that Caspar will be taken care of. Meanwhile, the aliens approach Jamila’s group. They start hitting the barrier with more strength. Alfie’s flamethrower does not help to kill or weaken them. But somehow, the group manages to save itself from those lethal creatures. They eventually find an abandoned train filled with several cars. Monty makes sure Penny gets to comfortably sleep inside one. Jamila is surprised to see Monty being so caring, while she knows him only as a bully. She starts feeling bad for dragging others into danger. He tells her to get some rest that she needs, just like others do.
