Al (Flatline)
From Tardis Wiki, the free Doctor Who reference
Al was a community service worker from Bristol. He was tasked with cleaning Rigsy's graffiti and the "murals" in tribute to those who had mysteriously vanished. When Stan was killed by the Boneless, he managed to escape along with Clara Oswald, Rigsy, Fenton and George. He witnessed George's death, although shortly after, Al himself was murdered by the Boneless. (TV: Flatline)
