Hey guys, I know this theory isn't as controversial as my last one, but here it goes: I think The Riddler is going to be an ally to Batman in the film.
Before you start getting confused or angry, let me state explain myself.
If you look in this picture from the Batman Vs. Superman trailer, you will see The Riddler's signatute question mark. We can also see what appears to be Batman standing and waiting(?) for someone. I beleive that person is The Riddler.
Now I understand that this could very well be just a little Easter egg put in there by the producers, but I seriously think that the calling card is there for a reason beyond that, but please let me know if you guys agree or disagree in the comments below. Thanks!
