While pure coincidence, a cameo from a Robin actor supports the concept of a connected multiverse where The Batman may feature a variant of Robin.
Warning! Spoilers ahead for The Batman
Thanks to a cameo from a current Robin actor seen early on in The Batman, a fun link to the greater DC Multiverse potentially exists. Directed by Matt Reeves, The Batman is set in its own universe apart from the DCEU. However, an unlikely (yet fun) theory has emerged thanks to an actor's shared credits in The Batman as well as in HBO's Titans (similarly set in its own version of Earth in the DC Universe).
In the first 15 minutes of The Batman, Robert Pattinson's Bruce Wayne is seen taking on a group of thugs on Halloween as the Dark Knight, emerging from the shadows to brutally take them out one by one. However, the brawl is preceded by the gang encouraging one of their younger members to jump a random bystander. Even so, the teenager hesitates as he's unable to go through with it. Likewise, this same gang member doesn't throw any punches once the Batman arrives while also calling out when one of the others pulls a gun on the vigilante who's proclaimed himself to be "Vengeance". Being the last one standing, the young man flees (with Batman letting him go).
Interestingly enough, this particular teen credited only as "Train Gang Young Member" is portrayed by Jay Lycurgo who also plays Tim Drake in HBO's Titans. In the comics, Tim Drake is the third Robin, a role which Lycurgo's Drake will be taking on with the show's upcoming fourth season. While it's more than likely a coincidence with no intentional connection on the part of Reeves or Warner Bros., the multiverse is a wonderful thing. For example, it's been confirmed that The Batman takes place on Earth-2 while the CW's Crisis on Infinite Earths revealed that Titans takes place on Earth-9. As such, fans are enjoying the theory that Lycurgo's gang member in The Batman is a variant of Tim Drake whose life took a darker turn (rather than becoming Robin).
There are some solid reasons presented as to why Lycurgo's gang member could be a version of Tim Drake. Not only does his reluctance indicate he still has a good heart that hasn't been fully corrupted, but he was also the single member of the gang who only had half his face painted with clown makeup, signifying the inner struggle within. Furthermore, the Dark Knight spared him from a beatdown due to Pattinson's Batman likely seeing the truth that the teen didn't want to be with the gang in the first place.
That being said, if Lycurgo's character in The Batman were to be a variant of Tim Drake, he'd have to have been born several years earlier than his Titans counterpart. After all, Batman's only in his second year as a vigilante in Reeves' film with no sidekicks to speak of, let alone a third Robin. At any rate, it's still a fun and interesting headcanon for fans of The Batman and/or Titans to think about thanks to the DC Multiverse.
