Question: When Scarlet Witch attempts to mind control Hawkeye, he turns it back on her and says something like "Already done the mind control thing...didn't enjoy it the first time." Was this supposed to be an in-joke reference to the fact that Jeremy Renner was publicly bitter about having to spend most of the first film being mind controlled by Loki (which almost got him fired)?
Question: Nothing very spoilery! The pool that Thor goes to with Erik Selvig - did I miss something, or was that just not explained much? It seems like he meets Erik, then they both go directly to a mystical lake in a cave that Thor just randomly happens to know about.
Chosen answer: The pool allowed Thor to relive the vision that Scarlett Witch made him see. It's through the vision that he finds out that Loki's staff contained an infinity stone and it would be to dangerous to destroy. He also sees the creation of Vision. He also sees that Asgard is in trouble. Since Selvig is an expert (as much as one can be) in Asgard and Earth he would be the one to help Thor find the pool. Many of the scenes relating to the pool were cut and could appear in the home release.
Question: Why is the Hulkbuster armour called Veronica?
Chosen answer: This is a fairly US-centric gag. In Archie comics, the titular Archie has two competing love interests: Betty and Veronica. Given the Hulk/Banner's history with Betty Ross being able to calm him down, Tony Stark has named the containment system/Hulkbuster armor "Veronica".
Question: Just wondering about something. Thanos sent Loki to Earth to recover the Tesseract, which contained an infinity gem. To do this he gave Loki a sceptre, which also contained an infinity gem. When Loki failed in his mission the sceptre was lost, so Thanos not only didn't get the Tesseract Gem, but also lost the Mind Gem, which he already had? Or did he not know the sceptre contained an infinity gem when he gave it to Loki?
Chosen answer: He knew. Most likely he planned to kill Loki after he conquered Earth. This is just speculation. We won't know fully until "Infinity War".
Question: What was Steve talking about when he said Ultron and Wanda and Pietro have something in common? Maria Hill makes it sound like Strucker, but it can't have been since Strucker had nothing to do with creating Ultron.
Chosen answer: They all resent Tony Stark.
Question: How is it even possible for Ultron to use Loki's sceptre to mind control the technician woman...considering that the sceptre came from Asgard and Loki is a god, whereas Ultron is a sentinel robot. Is this a goof?
Chosen answer: Loki is only a god by our standards (commanding incomprehensible power, borderline immortal, etc.) The sceptre contains a mind stone that can presumably be controlled by any sentient being, and Ultron is most definitely that.
Question: Why did Thor let Cap have some of his drink that he said mortal men can't have. I know that Cap's super soldier serum makes him stronger, but he's still human.
Answer: By mortal men, he probably just means ordinary. Since Cap has super powers, Thor doesn't consider him ordinary (plus the we learn in Captain America: The First Avenger that his advanced metabolism prevents him from getting drunk). Since Thor also relents and allows the WWII veterans to partake in the drink as well, it's safe to assume he doesn't consider it to be deadly for humans to have.
Answer: Cap now has a superhuman metabolism, as shown in the first Cap movie when he was unable to get drunk after Bucky died.
Answer: It is not specifically explained in the film, and at the end Thor believes Vision is worthy, whilst Stark and Rogers debate whether it is because he is an android rather than being "alive" that he can wield it. One possible explanation is that Vision does not have any ill intentions, even saying that he is too naive to even know if he is a monster or not. Because of this he could be said to be "pure" and therefore worthy of using Mjolnir.
Question: In the original Avengers movie, after Captain America breaks up the Thor/Iron Man fight, Thor goes to hit Captain America with his hammer, Captain blocks it with his shield and Thor goes flying. In Age of Ultron, they do the same thing intentionally in the opening battle scene, and it flips the tanks and vehicles but Thor is unaffected. Why the difference?
Answer: The first time it was unexpected. After that they realised it was a good military move. The way they did it, they most likely practised and have done it several times before. They said they've been hunting and destroying HYDRA secret bases for three years since the events of the first movie.
Question: When Wanda uses her powers on Tony, he sees his friends lying dead on the ground. Later, Tony says that what he saw was something that was actually going to happen? Why would Tony believe that the deaths of the other Avengers is something that would actually come true? Wanda was very good at messing with his mind so, she could have made him believe that their deaths would occur.
Answer: What Wanda did was to amplify Tony's existing anxiety about failing to protect his friends and the world. He was probably already having dreams and thoughts to that effect before encountering Wanda - when she used her powers on him, the resulting vision was so vivid, but in keeping with his previous fears, that Tony was convinced it was an actual premonition of the future.
Question: What was Steve referring to when he said he'd seen Natasha flirt up close?
Answer: He was implying she had flirted with him at some point.
Not just an implication. We see this explicitly in The Winter Soldier.
What was it?
Natasha is constantly flirting with Steve throughout the movie.
Question: Throughout the movie, the people in Sokovia speak English with an accent, and a previous correction claimed that the native language was English. So why are there signs all over the place in Russian?
Answer: Sokovia's official language seems to be Serbian (I've seen Ukrainian also listed), the writing seen is in the Serbian Cyrillic alphabet (some places it's the Latin script), which looks similar to Russian. It's possible that English is also an official or unofficial language, this is usually due to a country being ruled or controlled by the British Empire at some point, but for some reason they choose to require signs to be written in Serbian. However, the English we hear may be more of a filming technique for the audiences' convenience. That is to say, they are speaking a foreign language but we hear English (or whatever language you're watching the film in) rather than hearing a foreign language and then either reading subtitles or not know what was said. You see this often in films, such as a WWII movie where the Germans are speaking English even though everything is written in German. Some films are known to switch between filming styles where sometimes characters speak in English and sometimes they speak in a foreign language. And some films or shows will create a universal translator to explain why we hear everything in English (like in Guardians of the Galaxy where Peter has a translator implant in his neck).
Question: Thor discovers the underground tunnel and fights a couple of Ultron Sentries there. As soon as he defeats them, he suddenly throws his hammer upward and leaves. Why?
Chosen answer: Thor was back down in the fortress, along with Black Widow and Bruce. He was trying to find what Ultron was building. But, it was located in the city and Thor left once he found out there was nothing there.
Question: Why was Captain America unable to hold Thor's hammer? He fought to protect his country. He saved the lives of innocent people and wasn't afraid to back away from any kind of danger so he should have been able to lift it. Ultron said that the reason none of them could lift it is because they were all killers but that's really just speculation.
Answer: He can pick up the hammer, he didn't want to upset Thor.
Answer: He's able to move it just barely, enough to impress Thor. It's an enchantment on the hammer that requires a combination of strength and righteousness. He might not be there yet, but he's on the way. Thus the hammer moves more than anyone else could.
Answer: It's not an in-joke about real life. It's just a direct reference to Loki mind controlling him.
