Albert is a vampire. Albert was a nobody back when Herrick ran Bristol's vampires. In 2010 he is one of those jostling to replace him. After Herrick's death, he took over Herrick's job in covering up the vampire killings. Albert is not very intelligent, that's why Herrick never liked him very much.
Albert used to work for Herrick and he always envied Mitchell, since Herrick liked Mitchell more.
