In the extract from the third act of Hamlet, the protagonist and his mother are in his mother's bedroom. They are speaking, and Hamlet is making a comparison between his father portrait and his uncle's one. He represents his father as a man-like-God (he gave him characterizations proper to Gods like Jove other March).
After that Hamlet begins to criticese his mother and he shows to her what is happened to her.
Hamlet asks himself how the mother could marry his uncle. The queen doesn't want to listen to her son because he tells the truth.
