Question: In the opening scene, why was Luis not particularly bothered by the sudden appearance of a neighbor child in their house standing at the entrance to their bedroom? He reacts to her initially as though she were an overnight guest who had been sleeping down the hall and not as someone who doesn't live there.
Answer: He also likely knew her since Anna had a conversation with the kid earlier about "say hi to your mom for me'.
Question: Why was the zombie twitching in the fountain and couldn't get out when he was only shot in the shoulder?
Answer: The bullet severed part of the spinal cord.
Question: What did CJ mean when he said, "f*cking figures", before he blew himself up with some of the zombies?
Answer: "Figures" is an English expression of figure of speech about something happens and a predicament winding up a certain way. It's a play on the mathematical term of figures in an equation having a determined answer. If you follow the figures, of course you get what is comes as the answer. This is often used in real life situations as a figure of speech, where of course the stuff that happens leads to this. It "figures." So basically CJ was saying, "of course this is what happens."
Question: Ana gets in the bus to get Michael. He shows a chainsaw to her. Ana tells him that might be the most romantic thing anyone's ever shown her, then Michael says, "I'm trying here." Sorry for a silly question, but what does he mean by that? Try what? (01:20:45)
Answer: He's returning her sarcastic comment about being romantic with a sarcastic apology. "I'm trying here", as in he's trying to be romantic and he's sorry it's not coming out the way he intended. He doesn't actually mean it, the two are simply trying to break the tension with humor. Their rapport is somewhat flirtatious throughout the film, they have an attraction that might have developed more naturally were the world not ending in a zombie apocalypse.
I actually took it that Michael was saying he's just trying to do his best in general.
Question: Right before Frank dies and turn into a zombie, he said to Kenneth, "You want every single second." What does he mean by that? (00:55:35)
Chosen answer: I interpreted it as a reflection on his life and the lives of all those around him as his life drained from him. And that reflection is that as people we are always chasing something - goals, desires, a nice new car, a better job, a family with kids - but we are always left wanting something more. It's what keeps us alive and moving forward. As he dies, everything becomes illuminated and he realises this truth. I think it could also mean that he wanted to live every single second to experience as much as he could in life. But I prefer my first interpretation, so that's how I picture it.
Answer: I interpreted it as meaning a person wants every possible second to remain as a human.
Answer: I assume this is a very old question, but I always thought it meant with your kids. He wanted to wait to be killed until after he turned because he was all his daughter had left. So he wanted every single second with her, but it could just mean as human as mentioned here.
Question: In the scene after Glen saws Monica's arm off and Kenneth crashes the bus, I can't tell if Glen was dead before he sawed Monica or after, and I can't figure out what killed him.
Chosen answer: Glen was alive when he accidentally sawed into Monica. He was killed as a result of the crash.
Answer: I'd like to think that if I had somehow managed to survive an apocalyptic zombie uprising and then accidentally chainsaw'd into another human being I think that I'd die just from the shock.
Answer: Glen doesn't saw Monica's arm off. He just saws into her body which is what kills her and then Glen dies as a result of the bus crash and from accidentally murdering an innocent woman.
Answer: Since it's not addressed in the script or the film, any answer would be speculation. One could be that Luis is just a generally laid back person, and the appearance of a young child he knows is not enough to ruffle his feathers, even if she isn't supposed to be there. He also just woke up, so he could be a bit groggy and not fully processing the situation as quickly as he might normally. More likely, it's simply the way the scene was filmed; the director and actor didn't think it important to show Luis "bothered" by the girl's presence (prior to noticing the blood, of course).
