Plot Hole
So after Largo has his henchman hide in Bond's shower and try to kill him, Bond gets the upper hand on him and send him back to Largo after taking the ammo out of his gun. OK now at this point:
- Bond knows Largo is up to something and he knows that Largo knows he's up to something (he sent Largo's henchman back to him knowing the henchman would tell Largo everything that Bond knows)
- Largo knows Bond is onto him and knows that Bond knows that Largo in onto him (Largo would know this because the henchman he sent to kill Bond came back to him and told him that he failed)
Therefore why would Bond go to Largo's house for lunch a day later when both men know that the other one is up to something and they both know that the other person knows that they are up to something?
