9) Resolution Of The Robin Mystery
As we just mentioned, when we meet him in BvS, Ben Affleck’s Batman has been crime fighting in Gotham for a while. Long enough for him to train up his sidekick Robin, only to see him die at the Joker’s hands. Well, at least, that’s what we assume.
All of this has only been conveyed in a single brief scene in the movie, in which Bruce comes across an outfit that you can just about make out as Robin’s, adorned with Joker-like graffiti. Hardcore fans will be able to put two and two together and work out that the film is alluding to when Joker brutally killed Jason Todd, the second Robin, in the comics. General viewers, though, are given no context here.
Hopefully we’ll get an explanation about this in The Batman. The death of a young man in his care is a hugely dramatic backstory that needs to be properly mined. At last it would give us a fresh impetus for Batman’s pain, other than the boring old murder of his parents.
