Recently, we’ve heard that Tom Holland is regarded as a fairly bad security leak when it comes to details of the MCU.
What does seem to be clear is that there is something or somebody in Avengers: Infinity War that Marvel really wants to make sure we don’t know about.
Is there going to be an introduction of a new villain in the film or possibly a specific returning character they don’t want to tell us about?
It’s certainly a possibility, but it could also simply be that they’re not telling anybody anything in hopes that they can keep as many secrets as possible between now and next summer.
