Marlene

Marlene is the mother of Eddie Michaels and the birth mother of Olivia Michaels.

Unusual Proposal
Marlene was a close friend of Pat Michaels and his wife. After the couple had trouble conceiving, Marlene offered to be a surrogate. The couple took her up on the offer and Marlene gave birth to twins, one boy and one girl, without telling the couple she was pregnant with the twins. Pat and his wife took the girl while Marlene kept her son, moving to the Bahamas afterwards.

Eddie reaching out
Eddie mentions to Pat that his mom is sick, asking for help. Pat says he can't doing anything due to Olivia. Eddie then tells Pat that hiding everything, and what is later revealed being Olivia's birth, from Olivia will make it worse.

Death's Door
Marlene meets Olivia when her children visit her over winter break. Marlene notices Eddie first when he walks in, accompanied by Olivia. Eddie kisses the top of Marlene's head. Marlene notices Olivia standing in the doorway after and gestures for Olivia to come in. Marlene makes a weak comment about seeing her two children together in the same room. Marlene goes on talking about when she found out she was having twins and when Pat and his wife took Olivia. Marlene takes Olivia's hand and says that seeing her daughter all grown up made it the happiest day of her life. A moment later, Marlene's heart rate monitor flatlines, signaling her death.
