Of course, one thing that we specifically need to remember in this instance is that Zack Snyder might merely be toying with his fans with this Vero post.
He’s forcing us to question whether or not that Robin suit actually belongs to the second Boy Wonder, but he’s also not denying that it does.
In fact, after the release of Dawn of Justice in 2016, a Warner Bros. tour guide seemingly confirmed that the DCEU Robin is actually Jason, so at this point, it really comes down to what you choose to believe.
