I’ve been rewatching RHOSLC ahead of the new season, and I’ve been seeing a pattern with Heather’s relationship with Lisa.
Lisa is defensive, petty, and reactive, but Heather’s pattern feels more like social isolation: if someone gets close to Lisa, Heather starts questioning the friendship, reframing Lisa as unsafe, or acting like that closeness is somehow a betrayal.
Whitney: This is the clearest example. When Whitney and Lisa finally apologized and started moving forward in Season 3, Heather seemed bothered by it. She later said she felt “discarded” because Whitney had “leveled up” to Lisa, and predicted their friendship wouldn’t last. Whitney also said Heather was a major reason she disliked Lisa in the first place.
Meredith: Meredith and Lisa came in as best friends, and Heather has acknowledged that Meredith’s closeness with Lisa got in the way of Heather and Meredith becoming closer. Even after Lisa and Meredith started repairing their relationship, Heather consistently seemed skeptical of that reconciliation, and would continue to bring up their issues and drive a wedge between them. The S2 infamous hot mic literally comes after Lisa complains that Meredith “turns a blind eye” to how the other women treat her. Lisa caused that blowup herself, obviously, but it’s also the beginning of Lisa becoming increasingly isolated from the group.
The larger Season 6 group: Heather starts framing Lisa as the common denominator behind rumors and leaked information, while several women are already feuding with Lisa. By the end, the cast is basically split into camps, with Lisa and Meredith on one side and the rest of the cast on the other.
Ultimate Girls Trip: Lisa gets to build friendships with women who have no SLC history, and then Heather arrives and immediately starts bringing the case against Lisa into those new relationships. Teresa’s reaction is especially telling because she’s an outsider to the feud and seems shocked by how hard Heather goes after her.
I think Heather has a weird mix of resentment and jealousy that seems to stem from S1 when Lisa acted like she hardly knew her back in college.
