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. He nevertheless accepted Charlie Smith's invitation to join him as his date for the school 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)

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 Shadow Realm. (TV: Co-Owner of a Lonely Heart)
