Valkyrie (Tessa Thompson) will be looking for a queen to rule Asgard with in Thor: Love and Thunder, and Jaimie Alexander just volunteered Lady Sif.
Since appearing in Thor and Thor: The Dark World as Asgardian warrioress Lady Sif, Jaimie Alexander has charted a path to becoming a household name. As one of the strongest female characters in the MCU up until that point, she paved the way for the subsequent women of Marvel who would prove worthy heroes.
We haven't seen Lady Sif in the MCU in a while, but Jaimie Alexander hasn't forgotten her.
