Grace Zabriskie stars as Lois Henrickson on HBO's Big Love. Lois is Bill's mother and a descendent of the founding family of Juniper Creek, the polygamy compound where Bill was born and raised.
Lois married Bill's father, Frank Harlow, and was his second wife. Following the rules of the sect, Bill and Joey were given their mother's last name, Henrickson.
Lois [about poisoning Frank]: How can he suspect me when I didn't do anything? That's crazy!
Bill: Fine, fine. So who is gonna pick him up?
Lois: Why don't you go pick him up?
Bill: I hate him as much as you do.
Lois: Then maybe you did it!
Bill [about his father]: He's gotta get to a doctor.
Lois: No! Remember when he got his fingers caught in the fan? You said doctors and he was fine!
Bill: He needed 23 stitches!
