She is mentioned when Lavinia tells Don that he owes her after he tries to abandon her. When Meg McCaffrey asks who she is, Apollo replies that she is a dryad that Lavinia is ‘interested in’ like Meg was with Joshua. Apparently Don got Lavinia to leave her post for a picnic that Poison Oak was supposedly attending, however she wasn’t and Lavinia got into serious trouble.
Like all dryads, Poison Oak loves the environment and interacting with it.
Poison Oak has green skin and green hair, with pointy ears.
- Poison Oak is the first unseen love interest seen in the series.
