Anja Kaczmarek is a character in Known Unknowns.
Nadia Nazari Edit
Anja and Nadia start out as enemies. Anja is mean to Nadia because she's defending Summer. She thinks that Nadia stopped talking to Summer out of homophobia, so she wants to keep Nadia away from Summer. She never explains to Nadia why she's being mean, so Nadia doesn't understand why Anja treats her that way and thinks she's being unreasonable.
Once Anja discovers that Nadia only stopped talking to Summer because Allen manipulated her, she becomes much nicer and supports Nadia through her difficult coming-out. Anja even lets Nadia watch an episode of Passiondale with her, even though it's her favorite TV show and watching it is a special, personal thing. They bond and open up to each other while watching the show, culminating in a kiss. After that, they start dating, and Anja joins in on Nadia and Kaz's ghost-hunting.
Kaz Kaczmarek Edit
Anja and Kaz get along well, despite their very different personalities. Their social lives don't have much overlap: Kaz and Nadia are best friends, even while Anja and Nadia are fighting, and Anja and Summer are friends, but Kaz barely talks to Summer.
