I'm sure Greg Cox will appreciate the Richard Matheson nod in the title, "I Am Legends." And Shaun of the Dead fans will appreciate that the plan in the middle of a zombie apocalypse in London was to get to a tavern. (Was that set a redress of Al's Bar from Supergirl?) It's really weird to have a character like Constantine thrown into a hokey sitcom I-hate-you-let's-make-out scene. Oh, that's who the gray-haired guy with thick glasses was supposed to be. I didn't make the Romero connection -- I just noticed that there was a continuity error between shots, that he was behind Constantine and Zari in the close shot and still in front of them in the subsequent wide shot. At first I thought Gideon was downloaded into his brain. It quickly became clear that she was a hallucination, but I didn't realize she was Gary Jr. II until she started hopping. But if Gary hasn't seen Gideon's human appearance before, how did he hallucinate her looking exactly like she's looked in her previous appearances?
