Q: Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title
In the Avengers movie everyone seemed to know a great deal about the Tesseract. Even Hawkeye seemed to know that it is a thing which can make portals (he tells about the Tesseract that door can open from both sides). In Captain America The First Avenger Red Skull only used the stone for harnessing power. So how does everyone know about the Tesseract and its capabilities?
A:
How does everyone know so much about the Tesseract?
