Marvel fans are excited for 'Avengers: Endgame.'
One of the biggest mysteries of the movie is how Tony Stark and Thanos know each other.
According to ComicBook.com, there is a new fan theory to answer that perplexing question.
In Avengers: Infinity War, Thanos recognizes Tony Stark pretty readily and, when asked, Thanos simply says he is also cursed with knowledge.
According to the fan theory Tony Stark is different and Thanos is able to see something in him.
The theory goes on to suggest that this particular quality is why Doctor Strange gave up the Time Stone to save Tony from Thanos.
