“Charmed” made a serious change in Sunday’s episode. Mel erased her relationship with Nico, changing their timelines, and Maggie came clean about kissing Lucy’s boyfriend. They’ll have to deal with consequences in Season 1, episode 6.

“With Maggie (Sarah Jeffery) trying to make up with Lucy (Natalie Hall), she realizes that there is a new Kappa member she isn't familiar with,” the synopsis teases. Who is this mystery member? It isn’t clear, but they could be supernatural. On the other hand, it might be one of the many little changes caused by Mel (Melonie Diaz) erasing her relationship.

Macy (Madeleine Mantock) and Maggie are doing their best to help their sister cope with the loss of Nico in the episode, titled “Kappa Spirit,” but it won’t be easy. Maggie is hoping an investigation will help. She “enlists Mel’s (Melonie Diaz) help to find out what is going on” at her sorority, the CW logline teases.

The promo video for “Charmed” Season 1, episode 6 shows Lucy about to dump a pitcher of drinks on Maggie’s head. Mel stops time to allow Maggie to make a choice, but she can’t exactly disappear when her former friend is in the middle of embarrassing her. Watch the promo video below:

Meanwhile, Macy is still concerned about seeing that glowing red mark on Gavin (Ser’Darius Blain). She “invites herself to his birthday party to investigate,” according to the synopsis.

However, it sounds like Macy might get more than she bargained for. The CW is hinting that she’ll get to know a little more about her past as well. “Meanwhile, Macy is told a cryptic message about her past that she decides to share with her sisters, but her sisters have a secret from her,” the summary reveals.

International Business Times previously reported that Mantock already knows all the details about Macy’s history, and she’s excited for viewers to learn the twist. “I felt really, really pleased that I get to play with that at some point,” she teased.

“Charmed” Season 1, episode 6 airs Sunday at 9 p.m. EST on The CW.
