Question: How did blood drop reached Marta's shoes, even though it was too far from Christopher Plummer in the suicide scene? (00:53:50)
Answer: The rationale is that blood can travel quite far from an artery and her shoe therefore got the droplet on it even from the doorway - however it does seem to me that the filmic portrayal is lacking, since you don't actually see any instance of spray. Rian Johnson' script says "Blood gushes." What we see in the scene is that it is trickling down his cut - a bit.
Question: Spoiler! The scene at the very end, with Arthur locked up talking to the doctor/social worker - is that meant to be later, after he's been captured again, or is it a flashback to when he was hospitalised before, as was referenced earlier in the movie?
Answer: This is later, as the building appears to be Arkham. He's committed there instead of going to jail based on his insanity. It appears he is laughing about the death of Thomas Wayne, we see a flash of that scene again for a reason.
Question: I don't quite get how the Hoffa killing plays out. His son is there in the car, Frank and Jimmy go into the house, Frank shoots him, apparently not heard, then leaves the house...doesn't Chuckie Hoffa have questions? Like where his dad is for a start, let alone the gunshots he must have heard?
Chosen answer: First off his name was Chuckie O'Brian. Jimmy Hoffa wasn't his biological father, he was more in the nature of a foster father. Second, he probably knew what happened. What was Chuckie going to do? It was a sanctioned hit. And if he went to the police he would have ended up the same as Jimmy Hoffa. They put him in the middle of it to keep him quiet. If he goes after the people who did it, he's as good as dead. If he talks he could end up in jail with them, and the mafia will probably kill him anyway.
Question: When police scour the old neighbourhood, there is a shot of a man wearing some kind of huge metal suit. What was this suit used for? (00:46:53)
Answer: Most likely protective body armour.
Question: Anyone know what happened to William Lieberman and Lou by the end of the movie?
Answer: To add slightly to the other answer, evidently some of the blood in the scene had to be digitally removed for the film to secure a PG-13 rating, which explains why we don't see any actual spray/gush. But we are to assume that a drop managed to splash onto her shoe when he slit his throat.
