Beck (Clara Oswald and the School of Death)
From Tardis Wiki, the free Doctor Who reference
Mr Beck was Ravenscaur School's P.E. teacher. When he took his class running across the beaches of Ravenscaur Island he fell into a Sea Devil hatchery. He and his class were transformed into Sea Devils. (COMIC: Clara Oswald and the School of Death)
When scolding Clara Oswald, Mrs Mariner compared her to Beck.
Take Mr Beck, who joined us not long before you. He possessed a certain arrogance, but has since learned his lesson. Now, he's well and truly one of us.
