Am I reading this right?
Fish decides he's going to do something. He is then physically assaulted by Fineas, who is an alternate personality sharing Fish's body. Fish and Fineas have an argument, Fineas says Fish can't save the multiverse and disappears, leaving his goggles behind.
So, I'm thinking that the whole conversation between Fineas and Fish took place inside Fish's mind, and none of the others in the Pub Stub are aware of it--and the Fineas personality has just self-destructed.
Thoughts? Arguments? Alternate ideas?
