SPOILERS AHEAD from "Avengers: Infinity War," and also "Thor: Ragnarok."

"Avengers: Infinity War" ended with half of the planet being dust-busted by Thanos. So HuffPost asked directors Joe and Anthony Russo to reveal what other Marvel characters were alive vs. vaporized. Their "too spoilery" answer on Thor's ex Jane Foster (Natalie Portman) was probably the most surprising.

The Russos only answered definitively on a few characters -- Howard the Duck in "Guardians" is safe, Matt Damon's actor version of Loki died (Jimmy Kimmel will be happy to hear that), Betty Ross (Liv Tyler) of "The Incredible Hulk" died, Thor's Lady Sif (Jaimie Alexander) was also dusted, and Peter Parker's Aunt May (Marisa Tomei) is safe.

Some characters were deemed too spoilery to say definitively, including Shuri (Letitia Wright) of "Black Panther," Ned (Jacob Batalon) of "Spider-Man: Homecoming," and Korg and Miek (Taika Waititi) of "Thor: Ragnarok."

But it's safe to say those characters are either alive or will return from dust in "Avengers 4" since we know we'll see more from them. Shuri may even get her own movie, and Ned should be in the "Spider-Man" sequel next year. Plus, Marvel Studios boss Kevin Feige told Fandango, "We have plans for [Thor: Ragnarok's] Korg and Miek. When and where we'll have to wait and see, but we, like the audience now that they've seen them, can't get enough."

Thor : The Dark World Premiere - LondonHowever, the Russos also deemed it too spoilery to reveal what might've happened to Thor's ex-girlfriend Jane Foster (Natalie Portman) at the end of "Infinity War." Did she turn to dust or not?

HuffPost was "a bit shocked" that they couldn't comment on Jane, so Anthony Russo clarified: "When we say spoiler, [we mean] potential spoiler."

Jane was last seen in "Thor: The Dark World," and was referenced in "Thor: Ragnarok" when a fan told Thor she was sorry Jane dumped him. (Thor, of course, had a different take on how their relationship ended.)

In 2016, Kevin Feige said there were "many reasons" why Portman's Jane wasn't going to be in "Thor: Ragnarok." Natalie Portman followed that by saying "as far as I know, I'm done" with Marvel, although she wasn't shutting the door. Apparently the Russos aren't shutting the door either. Is that because she'll be in "Avengers 4," which the Russos directed, or is she possibly coming back to a future Thor movie?

Last we heard, Chris Hemsworth's contract as Thor ended with "Avengers 4." He was hoping to do more "Thor" movies, but there was no word on that front. Would they bring Jane back for another "Thor" movie, even if one happened?

This might all be news to Natalie Portman, too. Some answers, and probably further questions, will arrive with "Avengers 4" on May 3, 2019.
