10 Things We Learned From Arrow's Season 3 SDCC Trailer

7. Diggle And Oliver Clash

http://www.youtube.com/watch?v=dYYuFHpFnbM Oliver's very first confidant and ally was John Diggle, a former soldier-turned-bodyguard who was hired to keep the returning Oliver out of trouble. Soon, he found out that not only was he protecting a man who could take him in a fight, but he was becoming part of something bigger than himself. Up until now, Diggle and Oliver have only had a few arguments. The trailer released at SDCC shows the two having it out over an issue that clearly gets under Diggle's skin. With a baby DIggle on the way, it's possible that Oliver will feel bad about putting him in harm's way, which would obviously upset Diggle since he has spent his entire life in the line of fire. The irony is that we found out last season that Oliver probably has a kid out there that he doesn't know about thanks to his mother paying the girl to tell Oliver she had miscarried, which means he really wouldn't be able to justify protecting Diggle for the sake of his kid when he is putting himself in just as much danger with a child of his own.
