Domestic violence
From Tardis Wiki, the free Doctor Who reference
Domestic violence cases were something that Yasmin Khan had dealt with. While examining Iz's dead body, she noticed a pattern of bruises on her arm that reminded her of these cases. (PROSE: Gatecrashers)
Chloe Webber had an abusive father who would often take his anger out on both her and his wife, Trish. He died in 2011 after crashing his car. In 2012, he almost manifested from a drawing made by Chloe, due to Chloe's psychic link to a young Isolus. (TV: Fear Her)
