“9-1-1” boss promises major 'confessions' from Buck, Eddie, Tommy, and Maddie tonight (exclusive preview)

Co-creator and showrunner Tim Minear teases the revelations galore to come on season 8, episode 6 of the ABC drama.

Tonight's episode of 9-1-1 is titled "Confessions" — and co-creator and showrunner Tim Minear says it lives up to its name.

"In the cases and in the personal stories, there are a lot of confessions being made," he explains. Eddie (Ryan Guzman) "literally is in a confessional, confessing," the showrunner tells Entertainment Weekly, who previously promised that this week would explain Eddie's mustache as well.

In a preview clip from season 8, episode 6 exclusive to EW (below), Maddie (Jennifer Love Hewitt) and Chimney (Kenneth Choi) will also reflect on how Mara (Askyler Bell) — Hen (Aisha Hinds) and Karen (Tracie Thoms)'s foster child — staying with them for months affected their daughter, Jee-Yun. "Then Maddie has a little confession to make as well," Minear teases.

And the revelations don't stop there. Tommy (Lou Ferrigno Jr.) will also makes an "inadvertent confession" to his boyfriend, Buck (Oliver Stark).

"Tommy doesn't even know he's really making a confession until the end of the episode when everything becomes clear," explains Minear. "And then he confesses something about himself and their relationship. It's all confessions!"

The showrunner also teases that the episode features guest star Jonathan Silverman (The Single Guy!) playing one half of a married couple opposite his real-life wife, Jennifer Finnigan (Salvation). "Not only does he make a confession," says Minear, "he spills his guts."

Since this is 9-1-1, we'll assume he's speaking literally.

9-1-1 season 8, episode 6, "Confessions" airs tonight at 8 p.m. ET on ABC.
