These are all the offences that Claudius might be most nervous about. These particular offences could be perceived as a threat. To Claudius – not to Ophelia – because why should she be concerned about his ambition or pride?
The only person to whom Hamlet’s ambition could be a challenge is Claudius. He’s the only one standing in his way to the throne.
It feels like an indirect way to put Claudius on notice to say, “Hey watch out –I’m fueled by all this stuff and I could snap at any moment, Big Guy. And I haven’t had time yet or the space to really plan what I’m going to do – but your times a-coming Claudius.”
