Major spoilers for Thor: Love and Thunder follow.
Over the course of Taika Waititi's Thor: Ragnarok follow-up, the freshly-anointed Mighty Thor, aka Doctor Jane Foster, attempts to come up with a superhero catchphrase of her own. Jane fires out a few less than stellar efforts (though we quite liked "eat my hammer"), before finally coming up with one she's happy with... right before she dies!
As Jane succumbs to her cancer in Thor's arms, she whispers her catchphrase in his ear. The Mighty Avenger responds with a smile ("it's perfect"), but we don't get to hear what she said, and it sounds like we may never find out!
"That scene was really, really fun to shoot," Natalie Portman said of Jane and Thor's final exchange during an interview with Cinemablend. "And yes, there is a specific line, but I will never reveal it."
We assume Waititi and Chris Hemsworth (at the very least) also know what was said, so there's a chance someone will spill the beans down the line. As for Jane, we saw her pass on to Valhalla in the movie's post-credits scene, where she was greeted by Idris Elba's Heimdall.
Some have taken this an an indication that Foster could return, but we saw it more as a farewell to the character as she ascends to the afterlife. Of course, the introduction of the Multiverse means we could always see a Jane Variant in The MCU at some point!
Thor: Love and Thunder finds Thor (Chris Hemsworth) on a journey unlike anything he’s ever faced – a quest for inner peace. But his retirement is interrupted by a galactic killer known as Gorr the God Butcher (Christian Bale), who seeks the extinction of the gods. To combat the threat, Thor enlists the help of King Valkyrie (Tessa Thompson), Korg (Taika Waititi) and ex-girlfriend Jane Foster (Natalie Portman), who – to Thor’s surprise – inexplicably wields his magical hammer, Mjolnir, as the Mighty Thor.
Together, they embark upon a harrowing cosmic adventure to uncover the mystery of the God Butcher’s vengeance and stop him before it’s too late.
Directed by Waititi (Thor: Ragnarok, Jojo Rabbit) and produced by Kevin Feige and Brad Winderbaum, Thor: Love and Thunder is now playing in theaters.
