Thomas

''I never got to see her, not up close. Never got to hold her.''

Thomas is a minor character in Mabel.

Season One
Thomas is first referred to as The Visitor, who asks Anna Limón how to get back to town several times. He then continuously mouths get out at her, over and over.

He comes back a few weeks later and tells Anna his story. He had come to the Martin house lost years before and met Lily Martin. She had invited him inside and, though he never got to meet her, Thomas became the father to Mabel Martin. He cared about his daughter, but was now stuck in the Underhill, leaving him to die and be unable to escape; thus, when Lily died, Mabel's care was placed on Sally Martin. He tells Anna (in Spanish so the House cannot listen) that she needs to find a door, which eventually leads to her actions in Legacy and Underworld.
