Question: How would Aldrich Killian or Eric Savin know how to program or how to remotely control the Iron Patriot (War Machine armour) to deliver President Ellis to Killian at the impounded damaged oil tanker? Surely only the pilot or maybe JARVIS could control the armour?
Answer: This isn't the suit Rhodes took from Tony in Iron Man 2. It's a new suit, developed by AIM, Killian's company. That is why he was able to reprogram it to bring the president to him.
Question: Was the kidnapped official supposedly shot by the Mandarin a part of the whole extremis plot? I'm pretty sure Trevor didn't actually shoot him in the head for real but he's never mentioned again after his supposed killing.
Answer: Most likely, to preserve the illusion to Trevor, his gun held blanks and he did not really kill anyone. However, the official would be too dangerous a witness to be left alive, so Killian would have his goons drag him out and execute him in secret after the taping.
Question: When Jarvis comes back on, he says to Tony "I do quite well for a _____, but at the end of a sentence I say the wrong cranberry". I can't tell what he's saying where the blank line is. Can someone tell me what he is saying?
Answer: He says "I seem to do quite well for a stretch, but at the end of a sentence I say the wrong cranberry".
Question: Can someone explain the exact function of the ARC reactor in Tony's chest, because it seems to vary from movie to movie? Sometimes it powers the magnet keeping the shrapnel out of his heart (1,3 & Avengers), which is why he throws it away after surgery. However sometimes it appears to be powering his heart directly (1), yet he can go for short periods of time without it (2). Mainly, however, isn't it required to power the suit (1 & 2). The Iron Monger needed one (1), Whiplash & War Machine both needed one (2), but Tony's suits in 3 & Avengers appear to work even when he's not in them?
Answer: In all of the movies, it is keeping the shrapnel out of his heart. In the second one, he is suffering from poisoning, a side effect from having palladium in his chest. The reason he can go for a short period without it, is because the shrapnel won't sink into his heart immediately when he takes it out. The discomfort he experiences in 1 when it's removed seems mostly do do with the fact that Pepper removes something she shouldn't have. The power of the suit is a different story. The suit in the first movie (Mark I, II and III) are all powered by the reactor in his chest. The Mark IV is difficult to guess, but the Mark V (suitcase), VI and VII (Avengers) all have a separate power core, and the suits in Iron Man 3 are all powered independently as well.
Question: How could surgeons remove the shrapnel from Tony's chest when they were unable to before?
Answer: Advances in technology. Throughout the film series, we've seen improvements being made to technology, so it's entirely reasonable, particularly with Stark turning his considerable intellect towards the medical field in order to remove the Extremis infestation from Pepper, that he could have determined a safe method of finally removing the shrapnel.
