Kumail Question

Sprite asks him why he abandoned her, and he said he was sick of their lifestyle where he had to pick up and move his life every 5 years due to the not aging thing. So his solution is to become a movie star, where everyone recognizes him daily? Isn't that like the exact opposite of his point? What happens when he continues to not age, but now can no longer live anonymously in a different location?!

Unrelated, but speaking of Sprite--wtf was with that super "dramatic" scene where she stabs Gemma, who proceeds to just stand up and disintegrate the knife? What was the point of that?
