Jared Padalecki has expressed a sense of apprehension regarding his upcoming appearance in the fifth and final season of The Boys, particularly concerning his reunion with former Supernatural co-star Jensen Ackles.

In an interview with Business Insider, Padalecki admitted, “I don’t know a whole lot about it, which is effing terrifying.”

He conveyed uncertainty about the degree of interaction he will have with Ackles, who portrays Soldier Boy, a character introduced in the third season of the show.

“I don’t know what we’re doing. I don’t know if we, like, bump into each other. I don’t know much about it. They’re still trying to write and figure out who’s going to be there. But it’ll be the end of this month,” Padalecki revealed.

Details regarding Padalecki's character are currently undisclosed. Notably, Misha Collins, another actor from Supernatural, will also be featured in the forthcoming season. Padalecki credited Eric Kripke, the creator of both Supernatural and The Boys, with his decision to join the cast.

“I know Eric Kripke very well,” Padalecki explained. “I know ‘The Boys’ very well. He’s like, ‘Hey, you wanna come play?’ I’m like, ‘Yes, I think?'”

Padalecki emphasised his feeling of intimidation at the prospect of joining the series, stating, "It’s terrifying for me.”

He shared that he had informed his wife, Genevieve Padalecki, of the likelihood of playing "an unconventional character," and that she had encouraged him to accept the role.

“Literally my text to Eric Kripke was like, ‘Hey, if I’m getting naked, just give me like a month’s notice to eat broccoli and rice and chicken breasts, and all day long just sit there doing push-ups,'” Padalecki quipped.
