'Switched at Birth' season 5 episode 4 spoilers: Students make racist display for Black Student Union; Iris starts a hunger strike in protest

Tensions run high on the campus after threats against the Black Student Union are brushed off by the administration on the upcoming episode of "Switched at Birth" season 5.

Titled "Relation of Lines and Colors," next week's episode will see the continuation of the show's racism storyline. According to the official synopsis, Sharee (Bianca Bethune) and Daphne (Katie Leclerc) are horrified when they stumbled upon a racist display at the Black Student Union inside the campus. When the students responsible for it are given minimal punishment, Iris (Sharon Pierre-Louis) begins a hunger strike as a form of protest.

Sharee becomes more frustrated with how the school is handling the issue, while Daphne also receives an anonymous threat. Emmett (Sean Berdy) works on an art project and seeks help from Bay (Vanessa Marano), causing friction with Travis (Ryan Lane) who's already furious about the idea that John (D.W. Moffett) is preparing to replace him on the baseball team.

Cartermatt reports that the hour will explore more than just racism issues on campus. It's expected to be one of the most chaotic episodes in the season as it may lead to some important developments that move the story closer to the end.

This isn't the first time "Switched at Birth" tackled a sensitive real-life issue. Back in season 4, the series explored a campus assault storyline that received mixed reactions from viewers. Series creator Lizzy Weiss spoke with TV Guide, and she explained her decision to incorporate the campus racism storyline this season.

"The important thing for me is to just get a conversation going, to really try to have a lot of different sides represented so that the characters are all talking to each other and hopefully it creates a conversation off screen as well, like we did with campus assault," she said.

The fifth and final season of "Switched at Birth" airs every Tuesday night at 9 p.m. ET on Freeform.
