The Batman’s post-credits scene teases a mystery, probably?

Batman has returned to theaters with a new cast of villains, a new case to solve, and a new post-credits scene for the post-Snyderverse era.

Most of The Batman’s exciting sequel teases happen during the run of the actual movie, rather than in the credits. In that sense, this is more like a pre-Marvel superhero movie. The Penguin looks out over the city that he’s going to attempt to run, Catwoman leaves Gotham but with a good excuse to return, and The Riddler meets a new friend in his cell at Arkham Asylum.

The Riddler — at least, it’s probably him — types “Good Bye” then leaves the question mark behind the phrase. After that, a bit of text flashes for a very brief moment. And that’s it.

The text that flashes is tough to see in real-time, but a recording of it frozen at the right time reveals
