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

Example Input: During the first episode of Season 3 of The Walking Dead, I noticed the group is now very cavalier about taking down walkers:    This is a staunch contrast from the first season when they covered themselves in walker parts to get through Atlanta. I don't have that scene handy but, in my mind, it seems like they were very cautious in how they covered themselves (e.g. seemed like they were wearing HAZMAT suits).  I understand that, as time passes, the characters learn more Walker do's and don'ts; but I was under the impression if Walker blood got in their system, they would turn.  Is this true or have I imagined this rule?
Example Output: As of S03E01, does walker blood have an effect on open orifices/wounds?

Example Input: The 1977 movie Close Encounters of the Third Kind is truly iconic, and one of my all time favorites. But there is one thing I am curious about.  During the climax, we see the aliens returning many people to the Earth. Most of them look like they are from a time far behind. Also, the other things that the aliens return during the movie are all very old things (taken a long time ago) eg.- Airplanes in Mexico, a ship in Mongolia. However there is one exception -- the 3 year old kid -- Barry, who is taken away by the aliens and returned back soon thereafter (at the end of the movie).  How did this happen? What could be the reason for this exceptional behavior of aliens?
Example Output: Why did the aliens return Barry so soon, in 'Close Encounters of the Third Kind'?

Example Input: In the middle of The Avengers, the team is split up after coming together on the S.H.I.E.L.D. Helicarrier. Bruce Banner/Hulk end up in an abandoned warehouse. Thor ends up in a field. Shortly afterwards, Tony Stark determines Loki's next destination, Stark Tower. This information is never transmitted to Banner or Thor. However, both of them show up in New York City and join in the climactic battle. How did they know where to go?
Example Output:
How did Thor and Banner know where to go?
