That's not a real theory about him being in Nebraska. It's a reach on how Nacho doesn't die bc I don't want him to die, but he clearly will. No way Lalo lets him get away with it. So maybe that is the only scenario: Lalo somehow dies, but even then how do the rest of the Salamancas not implicate Nacho, the only survivor of the massacre at Lalo's house.
Still entertaining to read these posts.
He connects with vacuum salesman guy and gets a new identity. Gene Takavic finds out he's alive in Nebraska.
