Question: Why does the Station Inspector chase children who are on their own and threaten to send them to an Orphanage? Is that what it was like in the 1930s?
Answer: He's not making it a point to chase down random children - he's like a security officer at an airport. It's his job to apprehend thieves and troublemakers and keep the station safe, and he only threatens to send children to the orphanage if they don't have parents for him to return them to. Also, it's implied once he finally apprehends Hugo that his particular harshness toward orphans (and most of his character flaws in general) is due to apparently having been one himself. He spells out the kinds of lessons he was forced to learn by growing up without a family, explaining how he became so cold, bitter, and antisocial.
Chosen answer: It is more than likely an early form of our modern day child protection. Just as today if children are found to be at risk, they can be and are taken away by social services and put into foster care. In the film, orphans may have been seen as a plague in an area that attracts posh looking people in stark contrast to urchins in rags eating out of bins. Most European orphanages/care homes/hospices/whatever you want to call them at that time were no better than anything depicted in Charles Dickens 50 years previously.

Question: How could Shen know that Po would be the baby panda from the village attacked by Shen's army?
Answer: Since Po's father was presumably the only panda to attack Shen's wolves head-on, there's a chance Shen could have seen him. Plus in the flashback, Shen orders his wolves to attack Po and his mother before Po's father defends them both with his mallet.
Question: What exactly did Shane do to Bernie?
Answer: If you're talking about in the past, he actually didn't do anything. Shane was going to tease/hurt Bernie with the stick, but Bernie grabbed it. Shane then lied to the zoo about Bernie attacking him which led to Bernie being moved. Although prior to Griffin kicking Shane's ass, Shane ended up cutting Bernie in the face.
Question: At the apartment, Tintin can't find his magnifying glass and Snowy finds it for him. He says "Thank you" like he's annoyed at him. If he is annoyed at him, why is this?
Chosen answer: He must have thought that Snowy had found the magnifying glass and was playing with it. Like most dogs would do with a toy.
Question: Why did Juni leave the OSS again? Also, why does Carmen seem to hate him again? They got over that in the first movie.

Question: At the end, when Gnomeo and Juliet emerge from the rubble, Juliet is in perfect condition. After her fountain got destroyed, shouldn't her feet have broken off because she was still glued and Gnomeo wasn't able to free her?
Answer: The pedal she was glued to was most likely destroyed from beneath her, which freed her.
Question: Why do they not refer to Pooh as Winnie? His name is Winnie the Pooh.
Answer: In the original book, near the beginning when talking about Winnie it says "his arms were so stiff... they stayed up straight in the air for more than a week, and whenever a fly came and settled on his nose he had to blow it off. And I think-but I am not sure-that that is why he is always called Pooh."
Answer: "Pooh" is his name of endearment. If you think about the people in your life, maybe the people you went to school with, you might remember several who were referred to most often by their middle name or their last name, or some nickname or designation other than their first name.
Answer: TV Tropes mentions that the big eye might be an enormous alligator, because alligators are known to live in sewers.
Alligator eyes are different from what was shown in the movie.
