Why is he smiling?
Look closely at his face.
Because he's clearly not himself
Confirmed for Lex controlling Supes (possibly with kryptonite)?
My theory is
>Bat signal in background
>Day vs Night
>Lex is referencing the fact that he's controlling Supes and he's called Batman in to trick him into believing Supes has gone rogue, leading to the big clash.
This is from the end of the fight against Doomsday-Zod, Superman is happy Batman survived and is helping him get out of his severely damaged Batmobile. Why do you people assume every shot is of them fighting each other?
Feeling smug. "I got you, motherfucker".
Comes after Batman tried to wreck Supes, failed, and made a break for it.
"No more armor, no more distance between us for you to use to dodge with, no more getaway car. I got you."
