>>85075882To be honest, the e-mail had a set up.
Lex Luthor had a meta-human thesis where he thought that there were people other than Superman with powers running around. He went to meet with the senators from the anti-Superman committee precisely because he wanted to get their support to create a think-thank against these people.
Batman hacked Lex Luthor servers and got the information Lex had on these people, along with information about Superman.
Batman was interested in Wonder Woman's curiosity about the files, since she had stolen it before giving it back to him after not being able to decrypt the files.
Batman was about to fight Superman when he looked on the files and found about the other meta-humans, including Wonder Woman, something that was knew to him. He then send WW an e-mail with the files interrogating and threatening her.
This made WW get scare and attempt to flee the country.
So it wasn't just a scene forced in there without any set-up and it made sense in the grander plot.
