Dossier
Lori is Brian Heder's third wife. She is part of the household arrangement that makes the boatyard functional as both a legitimate front and an operational hub. The sangria is real. So is the rifle.
Brian's official bio places her at the center of the domestic setup that Jason has access to through his arrangement with Heder. That setup is part of why the operation works, a boatyard with a functioning household attached to it does not draw the same attention as one that is obviously just a front.
She handles weapons. Rifle and pistol, both in Trailer 2. Whether that's household protection or something closer to active participation, nobody's said. Either way, she's not standing around at that dock doing nothing.
