Abraham (A Town Called Mercy)
From Tardis Wiki, the free Doctor Who reference
Abraham was the local undertaker of Mercy, Nevada in 1870.
When the Eleventh Doctor addressed himself as "the Doctor", Abraham, believing the Doctor to be referring to Dr Kahler-Jex, began measuring his body for a coffin, as Kahler-Tek was tracking down Jex. He later offered fresh coffee to the Doctor after he became Marshal of Mercy. Abraham claimed to trust Isaac's reasoning in making the Doctor Marshal, and said that if the Doctor was good enough for Isaac, he was good enough for him. Immediately after saying this, Abraham began to measure the Doctor's body again. (TV: A Town Called Mercy)
