In the context of the underlying dramatic problem, none of that mattered. Nothing mattered in this story. None of those characters were important. Agatha All Along exists to set up another story. There's no dramatic weight to it. No stakes.
Stories don't matter because they lead to another story. They matter because they have something to say. What did Agatha All Along have to say? What meaningful choices did characters make?
The big, meaningful choice that it seemed like Agath was making was to finally put someone ahead of herself. But no, she's back a few minutes later, and arguably better than ever.
How so? Stories only matter if they have sequels? I mean, Hamlet 2 is pretty hilarious, but the original doesn't need it. Moon Knight doesn't matter because it was designed to be part of another story and then dropped (see The Eternals). A good story has something to say on its own.
Okay, so maybe in the future it will matter. If I also watch that show.
