Supergirl season 6 episode 4 is scheduled to arrive next week on The CW, with the title "Lost Souls." Kara Danvers a.k.a. the titular heroine (Melissa Benoist) is still in a tough situation and must find a way to get through her current situation. She must figure out how to escape the Phantom Zone.

Over the past few episodes, Kara has been separated from the rest of the team after being trapped in the Phantom Zone. But, it looks like she'll be reunited with everyone else as she found an opportunity to leave and go back home in the upcoming Supergirl season 6 episode 4.

While this is good news, that doesn't mean that her journey will be easy. According to the synopsis, Kara finds a way to escape the Phantom Zone but it comes with several dangers. It looks like Lex Luthor (Jon Cryer) remains to be the biggest torn on the titular heroine's side.

The early run of the current installment saw the Super Friends close to defeating Lex -- but they failed. He avoided going to jail and he's the one who sent Kara to the Phantom Zone, where she was forced to relive the trauma she suffered in the past.

Yet, she is determined to go back home and reunite with others, and she'll bring her father Zor-El, and her friend Nyxly (Peta Sergeant) with her. Now that she found a way and has companions on her side, the titular heroine may be able to escape Phantom Zone.

While Kara is gone, the Super Friends will also continue to deal with the threats looming around them in Supergirl season 6 episode 4. The previous episodes saw them having a hard team with her absence. Although they take can on certain evil forces, they know that they'll be stronger with Kara's presence.

Alex (Chyler Leigh) and J'onn (Davide Harewood) were particularly affected by Kara's absence, with the former losing all her hopes to bring her sister back. The good thing is that Kelly (Azie Tesfai) was there on her side and comforted her not to give up.

In Supergirl season 6 episode 4, Lena Luthor (Katie McGrath) has finally decided to join the Super Friends. But, while taking on their mission, she disagreed with their plans against the Phantoms and started to question her decision if she truly wants to be part of the team.

Lena has been trying to find her place and she wanted to prove to everyone that he is not like her brother, Lex. The process of becoming the better version of herself isn't easy, but she's working on it as she continues to piece herself together.

Supergirl season 6 episode 4 airs on Tuesday, April 20, on The CW.
