In the post-credit scene of Ant-Man and The Wasp, Janet van Dyne tells Scott Lang:
"Don't get sucked into a time vortex. We won't be able to save you."
Sometimes filmmakers will put in little Easter eggs like Serenity in Battlestar Galactica and I was wondering if there was anything in books, comics, etc. that would explain this.
Is there a connection to the Doctor Who and the time vortex in that universe? Or are the words "time vortex" just a coincidence?
