Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

[EX Q]: Near the start of Guardians Of The Galaxy, Rocket says about the Xandarians:    Xandarians. What a bunch of losers. All of them in a big hurry to get from something stupid, to nothing at all. Pathetic.   What does he mean by this?
[EX A]: Why are Xandarians in a hurry to get to nothing at all?

[EX Q]: Towards the the end of the last episode of Bodyguard series 1, the Chief of Police is watching a television news report summarizing the results of the investigation into the bombings.  The head of the Secret Service is then mentioned, and his picture is shown as being under investigation. Why was this character being investigated by the police, given that (spoilers follow):    The deadly bombing campaign was the result of an alliance between Islamic terrorists and organised crime, and was not an insider job by either politicians or the Secret Service.
[EX A]: Why was this character mentioned in the News in the final moments of Bodyguard?

[EX Q]: The protagonist in the Jack Ryan films is actually named JOHN Ryan. I'm not too familiar with the book version of the character, as I've only read a couple of the books. The movies don't mention where the name "Jack" comes from, but uses "Jack" as of his first appearance in "The Hunt for Red October", and even in "The Sum of All Fears", which is chronologically set much earlier. I'm hoping a fan of the series can shed some light on the origin of that nickname.  Do any of the films containing Jack Ryan mention where he picked up the nickname "Jack"?
[EX A]:
Where did John Ryan pick up the nickname "Jack"?
