A number of things, obviously. The Ghost is still bellowing "Swear!" from under the stage. And we can assume that Claudius is still partying as he was earlier in the previous scene. What else is happening, we don't know.
The Inciting Incident is when the Ghost makes Hamlet swear to get revenge on Claudius for murdering him.
He asks them to swear not to tell about the ghost's visit and why Hamlet may appear crazy.
It is "will swear." Example: "The man will swear if someone makes him mad."
As an example, the Ghost's line in Hamlet: "Swear!" It's the same word and the same meaning you know in the sentence "Do you swear to tell the truth, the whole truth and nothing but the truth, so help you God?"
Do you agree or disagree with Hamlet's assessment of man's reason for living
Swear before no man. Also you could say "Don't swear to God"
If you mean cool things about being a doctor; You have to swear an oath of secrecy regarding patient 'problems' and illnesses.
Hamlet's friend Horatio was most loyal to him. Furthermore, in Act 1, scene 5, Hamlet makes Horatio and Marcellus swear loyalty to him and to never reveal what they have witnessed in the woods and Hamlet's interaction with his father's ghost.
