Danny Pink

Rupert Pink, later Danny, was a soldier in the British Army, and afterwards a mathematics teacher at Coal Hill School, where he also established the Coal Hill Cadet Squad.

Biography
As a child, Rupert lived in West Country Children's Home in Gloucestershire for some time. One night, he had a nightmare of someone under the bed grabbing his ankle, and he met the Twelfth Doctor and Clara Oswald for the first time. They encountered a figure which the Doctor believed might be a creature that hides under the bed. The three of them turned their backs so the creature could leave unseen. After it departed, Clara attempted to put the child at ease by placing toy soldiers to guard under his bed. She designated one of them - which Pink had called "Dan the soldier man" - as the one in charge: a soldier so brave, he didn't need a gun. Rupert's mind was then scrambled by the Doctor to prevent remembrance of this encounter. He instead would only recall a dream where he was "Dan the soldier man".

Later in life, Pink joined the army, where he performed a number of humanitarian tasks, such as building wells, alongside traditional military work. (TV: Listen) Following his exit from the army, Danny would become distressed when mention was made of him having killed while a soldier.

Shortly after beginning teaching at Coal Hill School, he was introduced to Clara Oswald by Mr Armitage. She invited him to join her at Kathy's retirement party after work that day, which he initially declined — an act he immediately regretted. While reviewing this awkward moment to himself, Clara overheard him. Although this further embarrassed him, Danny gratefully accepted her offer to grab a drink together. (TV: Into the Dalek)

The two went for a drink at some point later, with mixed results. The couple argued several times, and Clara left twice, the second time when she was summoned by Orson Pink, whom she believed to be the Doctor. Despite these difficulties, the two shared a kiss soon afterwards.

Eventually, he would become the great-grandfather of Orson Pink. (TV: Listen)
