If it's crap ... We'll tell you
Before I get into this *SPOILERS* *SPOILERS* SPOILERS* for TDKR
Ok now that is out of the way. I have a question in regards to a possible Nightwing reference. After Gotham had been taken over and Blake was working with Gordon to track the trucks I noticed Blake would mark something on the way. Possibly a way for them to keep track of locations. During the climax of the move Gordon is tracking down the bomb. I noticed when he was in a location they had previously marked there was a blue chalk logo that kinda stood out to me. To me it looked like a possible Nightwing logo. Something that Blake may have come up with to mark locations. I'ven seen the movie twice and its definitely there and not natural to the brick. Thoughts?
