They don't have to show him changing him. They could show Algrim in muspelheim, and they can show him being like..engulfed in lava or something, then the scene ends. The implication is that SOMETHING in muspelheim changes him. As later on in the movie, it is revealed that Surtur rules muspelheim, then we can just put 2+2 together. I agree, there won't be a "full reveal" till after the credits I would say
