but December is found dead, hanged from the ceiling by the loyalists. Marilyn Dunham (portrayed by Amy Madigan and Ania Markiewicz) is Olivia's mother. While dead for many years in our universe, she is alive and well in the parallel universe, maintaining a close relationship with Fauxlivia. Rachel Dunham (portrayed by Ari Graynor) is Olivia's younger sister. She is the mother of Ella and resides with Olivia in a temporary living arrangement during season one, because of marriage difficulties. She seems to share a mutual attraction and several mutual interests with Peter Bishop which noticeably concerns her sister. However, following her moving out of Olivia's apartment in season two, nothing further develops between them. As of season three, Rachel has reconciled with her husband Greg, and lives with him in Chicago. The parallel universe version of Rachel died in child-birth along with her daughter. It is assumed that Alternate Rachel and Fauxlivia had a close bond. James Heath (portrayed by Omar Metwally) was one of the children that Walter and William Bell treated with Cortexiphan. The experiments left him with the ability to exchange energy with other Cortexiphan subjects.

Henry Higgins (portrayed by Andre Royo) is a New York taxi driver in the parallel universe, becoming an ally in Olivia's struggle to get back to her original universe. Amy Jessup (portrayed by Meghan Markle) is an FBI agent with the New York Field Office introduced in the first episode of Season 2. She quickly becomes interested in and involved with Fringe Division. She seems more open to the existence of extraordinary phenomena than most other outsiders to the group, though it is suggested at the end of the episode that this may come from a religious standpoint. Rebecca Kibner (portrayed by Tegan Moss as a teenager, and Theresa Russell as an adult) is a former test subject of Walter's. When still a teenager she willingly subjected herself to hallucinogenics. During these experiments she got in contact with parallel dimension; and thus it was through Rebecca that Walter first learned about the parallel universe and some of its characteristics. Most notably she gained the ability to recognize shapeshifters. She apparently grew very fond of Walter,
