People how can you guys not get obsessively happy about this?
these pictures have 'Red Hood' written all over them.
ALL OVER.
it's perfect
The 'dead' robin is definately going to be Jason Todd, but it'll turn out he isn't dead after all. Joker's 'THE JOKES ON YOU' batman in his lair will be because Robin isnt dead at all. And it'll be ROBIN/Jason Todd whom has written that on the suit, as Jason Todd will know batman's 'batcave' and secret identity.
It's perfect.
Just think about it:
Bruce is at Metropolis when Superman and Zod destroy his building, killing his employees whom Bruce probably see as 'Family'.
This will upset the Red Hood / Jason Todd, whom might have had somebody over there. He'll write Bruce a paper 'You let your family die',
which will shock Bruce.
Then he'll discover the spraypainted Robin uniform 'Joke's on you batman'.
All this together will motivate batman to come out of retirement.
This could be the point where SS movie connects to BvS
Batman, Harley AND Joker after all will be having their moments in SS.
I really could see this to be the very point that leads to the car chase.
