On Tuesday, directors of 2018's "Avengers: Infinity War" posted an image on Instagram of a cartoonish "2." This follows the "3" they posted Monday.

Although the directors didn't caption the image or explain it in any way, fans have decided the string of messages means that the long-awaited "Avengers: Infinity War" trailer will arrive online Thursday. Less than an hour after the "2" was posted, nearly 20,000 fans had liked the image.
