So you load the place up with C4 and drive off watching
the huge explosion in your rear view mirror. The next day the
morge calls you up to identify a body. "Yep that's him,"
you say, "that's the Riddler alright. His body is charred
beyond recognition and he's missing his face, but he always
has that dumb cane in his hand. I've always hated that cane."
Alright, you defeated The Riddler. Good job!
