Welcome to Plathville season 4 returned in May, and with Moriah Plath and Max Kallschmidt's breakup being one of the season's biggest story lines, fans are starting to suspect that Moriah's younger sister Lydia Plath is crushing on Max. He was first introduced to viewers on Welcome to Plathville season 2, after he began dating Moriah in 2020. By Welcome to Plathville season 3, Max and Moriah were planning to move in together.

Although fans predicted that Moriah and Max would go the distance after Max gifted her a promise ring, the fan-favorite couple ended their relationship in November 2021. The first few Welcome to Plathville season 4 episodes confirmed that Max was unfaithful after attending a party, and the rest of the season has documented their problems. While Moriah has chosen to take the high road by not revealing details of Max's infidelity, their breakup has noticeably hurt her.

While the Plath family has done its best to support Moriah amid her breakup with Max, fans are giving 18-year-old Lydia the side-eye. Although Lydia and Moriah have a close bond, Redditors tuning into Welcome To Plathville's June 28 episode noticed several signs which indicate that Lydia may be crushing on Moriah's ex-boyfriend. Here's how Lydia's behavior on season 4 is raising red flags among viewers.

Lydia Wants To Hang Out With Max

Welcome to Plathville Max and Moriah Plath

Fans aren't pleased that Lydia is still interested in being friends with Max, especially because Moriah has made it clear that the idea makes her uncomfortable. Although Lydia doesn't have as much life experience as Moriah, Max, or the rest of her older siblings, Welcome to Plathville viewers say that Lydia has no excuse for crossing Moriah's boundaries. "Duh, Lydia! Not cool to hang out with the ex of your sister!" one user stated, while another described the 18-year-old as, "not socially mature and experienced enough to see other people's perspectives."

Lydia Forgave Max For Cheating On Moriah

During one conversation with Lydia during the recent Welcome to Plathville season 4 episode, Moriah explained that she had chosen not to forgive Max because he cheated and then blamed their relationship's demise on her. In response, Lydia admitted that she forgave Max for his transgression, and that is part of the reason why she stays in contact with him. Fans aren't buying this, however, and think that Lydia is inappropriately getting in the middle of Max and Moriah's former relationship. Several Redditors ranted about it not being Lydia's place to forgive Max, and many praised Moriah's restrained response. "Moriah did an amazing job not yelling. If that was my sister, I would’ve called her out and made a scene," one user stated.

Lydia's Conversations With Moriah Don't Seem Sincere

Although Lydia apologized to Moriah for overstepping her boundaries regarding Moriah's breakup with Max, viewers tuning into Welcome To Plathville just don't believe that Lydia's conversations with Moriah are authentic. While fans of the show are equally angry at Max and think that he is using Lydia to get at his ex-girlfriend, several Redditors hypothesized that Lydia is forcing her demeanor. A few also compared Lydia to her mother Kim Plath, who just asked for a divorce from the Plath patriarch, Barry. "[Lydia] always seems pretentious and disconnected from herself even. It’s like she doesn’t know how to be genuine," one user summarized. With so many relationships imploding on Welcome to Plathville season 4, it will be interesting to see if anything more happens between Lydia and Max.
