Matteusz Andrzejewski

Matteusz Andrzejewski was a student at Coal Hill Academy in 2016. He was gay and as a result experienced conflict with his deeply religious Polish parents, (TV: For Tonight We Might Die, Nightvisiting) although he was close to his grandmother, who called him "Matti". (TV: Detained)

Biography
When he began learning English, he would read books in the language, including a book about a place called Narnia, at his mother's suggestion. (TV: Detained)

In 2015, Matteusz visited his grandmother in Poland for her birthday, with his father, and finally admitted his homosexuality to her. She had always known, but wanted to hear it from him. (TV: Detained)

In October 2016, Matteusz accepted Charlie Smith's invitation to join him as his date for the Autumn Prom.

He survived the Shadow Kin attack on the night of the prom, and was among the few students who met the Twelfth Doctor. (TV: For Tonight We Might Die)

According to Charlie, Matteusz was grounded when a dragon monster was attacking the school. (TV: The Coach with the Dragon Tattoo)

Matteusz's body was taken over by Steve Hopley, with two other "joyriders" taking over April and Tanya's, to kidnap Charlie and Miss Quill, using the alien body-swapping technology stolen by Garry Fletcher. James Banks, who was controlling Tanya, threatened to kill Matteusz's body in order to coerce Charlie and Miss Quill into following them to the alien machine and fixing it. Matteusz was eventually returned to his body. (PROSE: Joyride)

He was thrown out of the house by his parents for his relationship with Charlie. (TV: Nightvisiting) He subsequently lived with Charlie and Miss Quill. (TV: Nightvisiting, PROSE: What She Does Next Will Astound You) On his first night staying there he admitted to Charlie that he loved him, and the pair ended up having sex. After Charlie saw his parents due to the Lankin's influence, he helped Charlie and Miss Quill defeat the creature, discovering on the way to Tanya Adeola's flat that every time he severed part of the creatures roots they immediately reattached. (TV: Nightvisiting)

Following Tanya's request, Matteusz with the others went to check what was wrong with an old stone house. When April was knocked unconscious, he dialled 999 to call an ambulance. During his second visit to the house, Matteusz was attacked by Charlie's doppelganger, which turned into dust from the touch of real Charlie. Later that evening, Matteusz and Charlie were completely cocooned in spiderwebs by the female bone spider. They were released by DC Carpenter. (PROSE: The Stone House)

In an effort to understand human Internet culture, Charlie posted pictures of Matteusz nearly nude. Matteusz was greatly upset by this, especially because he did not know Charlie has even taken the pictures, and did not forgive him until the next day. (PROSE: What She Does Next Will Astound You)

He became interested in the ornate box in Charlie's room, and asked him about it. Charlie showed him the contents of the Cabinet of Souls, and explained the legends of his people that the box could be used as a weapon to kill or possess a whole race. Matteusz didn't like this as it would lead to a genocide. This upset Charlie. He was the first of the Coal Hill defenders to notice the killer petals that were appearing around the school and how they were increasing in number. He went with Charlie to April's house just in time to see her travel to the Underneath. (TV: Co-Owner of a Lonely Heart) When Miss Quill and Dorothea Ames took Charlie and him to their house in order to persuade Charlie to use the Cabinet of Souls to kill the petals, Ames pulled a gun on Matteusz to motivate Charlie. Matteusz was adamant that using the weapon was mass murder, but surreptitiously texted Tanya "Shadow kills petals", having realised that the Shadow Kin could be used to kill the petals. Whilst Charlie was arming the device, Ames had turned her back to Matteusz and he used that to his advantage and knocked Ames out, remarking that he really didn't like guns. After Charlie disarmed the weapon, Charlie confessed that he might have lost what made him him; Matteusz told Charlie that if he was ever lost, Matteusz would find him. (TV: Brave-ish Heart)

He was placed in detention by Quill to get him out of the way, when a meteor brought the classroom he and the others were in into no-time, no-space. He was the first to notice the meteor that contained the Prisoner embedded in the wall. When he touched the meteor he confessed that he was afraid of Charlie as well as loving him. This upset Charlie but he managed to bring him round using a story from his youth. Later Ram had a confrontation with him, as Ram, affected by the Prisoner, thought that Matteusz had some weird sexual fetish being into an alien. When Charlie had a panic attack Matteusz had to calm him down. He got concerned when Charlie said that he wanted to used the Cabinet of Souls to destroy the Shadow Kin, but discovered that it was Charlie's love for Matteusz that stopped him. Charlie killed the Prisoner, bringing the class back to Earth. Quill revealed to Charlie and Matteusz that she had had the arn inside her head removed, restoring her free will, and said that things were going to change around there. (TV: Detained) Quill immediately fainted in front of Charlie and Matteusz afterwards, and they realised she was heavily pregnant. (TV: The Metaphysical Engine, or What Quill Did)
