Comedy of errors, adrianna/ marriage assignment

In a rage, Antiphonal is about to break down the door when Blathers dissuades him, telling him that doing so will reflect badly on his wife’s honor and that Adrian must have a good reason for keeping him out. Infuriated Antiphonal leads his friends away, resolving to dine with a courtesan at her house, the Proportion. He asks Angelo to go fetch a gold chain, recently made, that he ad promised to his wife; Antiphonal now plans to present it to the Courtesan instead.

He does this because as we see the gold chain would have much meaning to his wife. Antiphonal was going to show her how much he loved and cared for her through the chain, but because he is mad that Adrian will not let him into the house he feels that he can just give away the necklace, because it was more than likely only to appease Adrian and keep her happy, because he had been late to dinner and didn’t want her to think that he had been off cheating on her.
