The M A N I A experience promised to be a show unlike any other, and Fall Out Boy absolutely delivered. Between interactive stuffed animals, countless selfie opportunities, a pop-up shop and a confession room, Fall Out Boy’s stadium gig couldn’t have gotten better. That is until Adam Siska popped out.

In an Instagram post, Adam Siska shared a photo of him and Fall Out Boy bassist Pete Wentz.

“Meeting those guys in 2002 absolutely changed my life,” Siska says.  “I’m honored to have been a part of a special event like this one.

Whether this news points to a possible the Academy Is reunion or not, the appearance has us super emotional.
