It seems like "they" give Brock the symbiot in the hospital scene, rather than how he gets it in the comics. The accident presumably is where the symbiot is found, then we see it carted away, then we see Brock essentially bonding to it.....maybe. I'm very curious as to how they incorporate the "spider-man" look and abilities if Parker never bonds with it. I really hope it's not by Brock watching spidey on the news and wanting to mimic him.
