|Appearance(s) :||Dead in the Water|
|Actor/Actress :||Amy Acker|
In May 2005, Andrea's husband Christopher took their son Lucas out swimming on Lake Manitoc by their lakeshore home, and Chris drowned and disappeared and Lucas was left mute and socially withdrawn afterwards from everyone, including Andrea.
When Sam and Dean Winchester came to Lake Manitoc investigating the drownings at the lake, Andrea showed them around the town and introduced them to Lucas, and was shocked when Lucas came to begin to interact with Dean.
One night, while Andrea was taking a bath, the Ghost of Peter Sweeney attempted to drown her in the bathtub, before Sam and Dean arrived and saved her. The next morning, Andrea discovered to her horror that Peter had attempted to kill her because her father Jake had drowned Peter as a child.
Shortly afterwards, Peter pulled Lucas into the lake, but the boy was released when Jake sacrificed himself, and saved by Dean. Just before Sam and Dean left, Andrea and a recovering Lucas bid them farewell.
Andrea seemed to have a slight romantic interest in Dean.
