Matteusz Andrzejewski's father
From Tardis Wiki, the free Doctor Who reference
Matteusz's father was deeply religious and did not approve of his son being gay. He argued with his wife about this. She almost accepted him, but he was too stubborn, so Matteusz was thrown out of the house. (TV: For Tonight We Might Die, Nightvisiting)
According to Matteusz, before this event, his parents would always go to parents' evening. (TV: Co-Owner of a Lonely Heart)
