The Hamlet Project

As far as we know, the last time Gertrude saw Hamlet was right after he killed Polonius. She may have feared she’d never see him again. I mean, sea travel was clearly not without peril, as evidenced by the pirates that turn up – and maybe she even has a glimmer of what Claudius was up to with this England thing.
She has had, theoretically, some suggestion of Hamlet’s return via the letters – but we don’t know how much Hamlet has told her. Maybe just “I’m alive.”
Anyway – there’s a lot that she may be feeling at seeing her son again grappling in the grave she just threw flowers in. Does she feel like she called him there by saying his name?
A line like this offers so many possibilities.
