Question: Loki (as Odin) quotes a conversation that occurred between Thor and Odin. This conversation happened after Loki let go of the handle Thor offered to keep him from falling off the bi-frost. How does Loki know what Odin tells Thor when he's supposedly headed to Midgard (Earth) as they speak? Can Loki read minds? If so, I don't recall any movies he comes out in mentioning mind reading.
Question: Several items thrown into the portal at the abandoned warehouse comes back through another end. How exactly do the items manage to get from the other dimension back through the other end of the portal?
Chosen answer: As seen in the film, the portals are in flux. They are constantly activating and deactivating, potentially pulling items through from one dimension to another.
Question: What exactly is the relationship between Jane and Darcy? Are they friends? Because Jane doesn't seem to like her much.
Question: In the end of the film, the Collector says to himself "One down, five to go." Does he have intentions for the Infinity Stones as well? Or is he just trying to collect them all, being that he is "The Collector?"
Answer: As his name suggests, he is just a collector and his ambitions don't go much further than that. Although it possible with all 6 he might use them to collect even more powerful objects.
Question: How did the rainbow bridge get rebuilt? Did I miss the explanation somewhere?
Answer: I think the implication was that it was two years since the destruction of the Bifrost bridge, and that appears to have been time enough to rebuild it using the Tesseract, which was brought back by Thor. Jane is the one who gives out the 2 years reference when remonstrating with Thor about disappearing.
Question: Is there any explanation to why several items thrown into the portal in the abandoned warehouse comes back whilst other stuff thrown into the portal doesn't?
Chosen answer: No explanation is given, but the answer is onscreen. When Jane and Thor walk into the cave after meeting Malekith, they find the other objects that were thrown into the portal that didn't return. Jane doesn't offer an explanation of how, but understands the implications of returning home. Given the fluctuating gravitational fields, we can only assume that the times at which objects entered the portal were the differentiating factor. It should also be noted that everything thrown through the portal was some kind of metal, so that might be a factor.
Question: The Bifrost was destroyed at the end of the first film and Thor was sent back to Earth another way in The Avengers. So can someone explain to me why he didn't visit Jane then? Or at least after Loki's plans were foiled?
Answer: Loki has been shown to exhibit numerous powers in the movies that can explain how he knew about this conversation. In all the movies, he has been shown to appear in hologram-like forms in different locations. For example, in The Avengers, he uses this power to meet up with The Other who is in the middle of space, whilst he is on Earth. In the end credits scene for Thor, he was able to watch over Selvig and Nick Fury's conversation despite not being there. In Thor: Ragnarok, he was able to see into Valkyrie's past through touching her head (though this power was not established until Thor: Ragnarok). Any of these powers could have been used to find out about this conversation between Thor and Odin.
