Arlo Thacker

Arlo Thacker is a former member of the Pine Guard who went to Sylvain to study the feral Sylvans living in the corrupted lands outside of the city and never returned. He was eventually discovered in a feral state and brought back to Amnesty Lodge by Mama, six years after his initial departure. For his safety (and everyone else's) he was kept in a kitchen alcove in the cellar of the lodge. The area is covered by a large net, which is made up of threads described as "shimmering." He was brought out of his feral state and is now played by Clint McElroy.

Physical Description
Thacker is described as "an older man with unkempt wild gray hair and [a] ratty-looking beard." He is said to be wearing a tattered button down shirt and khakis, and is described as having a black sheen of sorts over his eyes.

Personality
Thacker, post-Sylvain, is almost entirely feral, exhibiting aggressive behavior and animal-like traits. While captive, he sits folded over his knees, head lowered, staring at the floor. However, when the net is removed, he begins to climb onto the ceiling and rotate his head almost 180 degrees.

He seemed to be possessed in some manner by some unknown entity, which communicated with Aubrey and referred to Thacker as an "unintentional host".

In episode 29, he was brought back to his former state by Aubrey's magic.
