Ever since it was announced “Pitch Perfect” star Brittany Snow would be heading to “Crazy Ex-Girlfriend,” fans have been dying to know how the a capella triple threat would fit into the CW’s musical TV series. On Friday (Nov. 18), her role was finally revealed, during the last few minutes of the episode, “Why is Josh’s Ex-Girlfriend Eating Carbs?”

While she only teased a few notes, we’re guessing Snow’s upcoming featured music video will be a song reminiscent of Miley Cyrus’ “Wrecking Ball” — for she is playing the role of Anna, Josh’s new love interest.

Aca-what? Yeah. After Josh (Vincent Rodriguez III) sang an entire song about how he could live on his own, and went on and on about how he should really be single for awhile, a hot hippie blonde from LA waltzes into his life. This type of situation couldn’t be more on-brand for Josh. Of course he would fall into a relationship with a gorgeous girl that’s way out of his league without even trying. Worst of all? He won’t even recognize his dumb luck. Josh just thinks this is how the world works.

But who’s to say Anna will be as doting and caring as Josh’s ex-girlfriends? Anna might give Josh a run for his money — or, to Rebecca (Rachel Bloom) and Valencia’s (Gabrielle Ruiz) chagrin — Anna could be awesome. That perfect combination of confidence and compassion, with a great sense of humor. Maybe she’ll become friends with everyone. It will be hard to hate her if she’s really great. If Rebecca and Valencia can find common ground and become friends, it’s not out of this world to think this Anna couldn’t join their current squad.

But Snow has only signed on for three episodes, and we’re talking about Rebecca and Valencia. The same two girls who revenge-peed on Josh’s music equipment. Rebecca will most likely want to sabotage Anna in some big dramatic way, while Valencia will probably try to pretend she doesn’t care at first, and date a random guy just to make Josh jealous, but then collapse in a mess of her own lies. Whatever nonsense they get into, it’s nice to know they’ll have each other, and Heather (Vella Lovell), to lean on.

What about Paula, you ask? Saving the worst bit of news for last, Paula and Rebecca’s current breakup is more heartbreaking than the fact that Greg (Santino Fontana) is gone forever — which showrunner Alina Brosh McKenna confirmed to ET.

“The show’s about the pursuit of happiness, and ultimately [Greg’s] happiness would be elsewhere from [Rebecca]. So we’d always talked about doing that, and we knew it was going to happen this season,” Brosh McKenna says. “Luckily, Santino was on board with him, so we worked with him… on the right timing of it. He was fine with it and he embraced it, and he got a lot of great songs going out the door.”

It’s beautiful that the one person who seemed like he’d never get free of West Covina escaped to greener pastures, but it’s ugly to see Rebecca and Paula’s (Donna Lynn Champlin) friendship breaking apart. Watching their forlorn, yet hopeful glances towards each other at the donut shop, it’s so clear they want to be together!

It’s just such a classic example of how hard it can be to stay close when we’re in vastly different stages of life. Paula has always been the more nurturing of the two — but as a mother and wife, with a full-time job and now going to law school, she doesn’t have the time or energy to feed Rebecca’s narcissism.

However, Rebecca has asked Paula numerous times what’s up with her, and she never gets a real answer. How can Rebecca be there for her if she has no idea what’s going on? It’s far past time for Rebecca to become a more observant and better caring friend to Paula — but we need Paula to open that possibility to Rebecca just once more before permanently shutting the door on their friendship. Because let’s be honest, screw Josh and Greg: It’s the love between Rebecca and Paula we ship the most.

“Crazy Ex-Girlfriend” airs on Fridays at 9 p.m. ET/PT on the CW.
