Birds of Prey reveals that another member of the Suicide Squad escaped Belle Reve. Belle Reve is a prison facility in Louisiana, used to store some of the world’s most dangerous - and powerful - criminals. It’s also Amanda Waller’s favorite place because she tends to keep an eye on the inmates and forcibly recruit them into Task Force X - the Suicide Squad.

In theory, Belle Reve is supposed to be practically impregnable. It has state-of-the-art security, customized to keep even the most hardened villains behind bars. This is no one-size-fits-all prison; after all, at any one time it could be holding anyone from Harley Quinn to Killer Croc. As a result, breakouts are expected to be a lot rarer than at Arkham Asylum, which sometimes seems to have a revolving-door policy to its various prisoners. Still, in Suicide Squad Harley Quinn eventually broke out with a little help from the Joker.

It seems she isn’t the only one. Birds of Prey features a scene in which Harley Quinn raids a police station, and she pauses for a moment to admire a wanted poster. “Hey, I know that guy,” Harley declares - and so do viewers. It’s Jai Courtney’s Captain Boomerang, another member of Harley’s Suicide Squad team. He’s clearly managed to break out of Belle Reve and has resumed his life of crime.

Most of Task Force X were Batman villains, but Captain Boomerang is the exception; he’s traditionally a member of Flash’s rogues’ gallery, albeit not exactly one of his greatest nemeses. The DCEU’s Boomerang is pretty comic book accurate, launching a crime spree in Central City. This brought him to the attention of the Flash, a rookie superhero who had yet to catch Batman’s eye and become a member of the Justice League, and Captain Boomerang was taken down with ease. The Suicide Squad novelization fleshes this out, revealing the two had already clashed several times before Captain Boomerang wound up in Belle Reve; the novelization’s canonicity is disputed, but it may suggest he’s already headed back to Central City for another round.

Birds of Prey puts a surprising amount of effort into stressing its connections to Harley’s big screen debut. Although Suicide Squad was a box office success - grossing over $746 million worldwide - it wasn’t exactly well-received. For all that’s the case, Birds of Prey still positions itself as the continuation of Harley Quinn’s story and presents Captain Boomerang as another subtle link between the two.
