In Independence Day 2: Resurgence, you're the Super Intelligent Hive-Mind Queen. Over a billion entities can be attached to your brain, but far less seem to be in this sequel than the first, so you should have even more available mental power.  Your Mission: Capture and destroy your arch-nemesis and only real threat: The AI Sphere.  Your Situation:  Your mothership has been cold-nuked from within by a valiant ex-President. All of your support staff is assumed injured or dead. Your Primary Planetary Objective is almost complete (mere minutes to go). This will result in the imminent Destruction of the Planet. Better be outside of Earth's gravity well in the next 30 minutes!! You are continuously being strafed by several fighter craft. You are in an inhospitable climate, running across difficult terrain, and you have just crash-landed at several G forces, so maybe you are not at peak physical health? You know exactly where the AI Sphere is. [With Jeff Goldblum], or so you think.  Why do you expend so much time and energy inefficiently chasing a school bus?
Why did the Queen chase the school bus?

In the movie The Hunger Games: Catching Fire, Beetee (played by Jeffrey Wright) comes up with the plan to wrap a wire around the "Lightning Tree", and plant the other end of the wire in the water at the pond (to electrocute their opponents). The group leaves the pond and hikes quite a distance to the tree. They wrap the wire around the tree and then send Katniss back to the beach with the other end of the wire.   So, since they start at the beach, why didn't they leave one end there, rather than repeating the entire hike all over again?  I understand they wanted to separate Katniss from the group.
Why didn't they leave one end of the wire at the beach?

In Season 3 Episode 6 Sansa is dragged all across the story, for who she's supposed to marry. I don't quite understand why she's so important. Because there is her brother Rob, who is the King of the North and Lord of Winterfell. And if he fell wouldn't all of that go to Bran (although he may or may not be alive according to their knowledge)?

Why is Sansa Stark so important?
