Well, to be perfectly obvious, Richard is screwed. He is certainly going to meet with his defeat by Bolingbroke in the near future. In scenes two and three Richard makes it quite clear that he is aware of his imminent doom. As a result of this he tries to play it cool and act like he can perhaps defeat Bolingbroke, though his brave front starts to break down fast when he is met by Bolingbroke in scene three. His "Sorrow and grief of heart makes him speak fondly [foolishly], like a frantic [an insane] man." (Northumberland 3.3 line 184/185)
At this point Richard is still the head of England, therefore being the representative of the country. Though he really does an ill job of it. I love the gardeners in the final scene of this act. (At least how I understand them to be, I could be way off from what Shakespeare meant for them to convey) I love how they use the metaphor of a garden and garden tending to talk about how the King has run the country and ultimately brought about his own end through his laziness. "O, what pity is it that he had not so trimmed and dressed his land as we this garden! We at time of year do wound the bark, the skin of our fruit trees, lest, being over-proud in sap and blood, with too much riches it confound itself. Had he done so to great and growing men, they might have lived to bear, and he to taste, their fruits of duty. Superfluous branches we lop away, that bearing boughs may live. Had he done so, himself had borne the crown, which waste of idle hours hath quite thrown down." (Gardener 3.4 lines 56-67) Richard has meant very little to his subjects, because they all have been able to see him for what he is. A very foolish man who is unfit to rule.
I think his end is going to be drawn out. I predict Bolingbroke will have him live to see the crown pass to himself (Bolingbroke), and then execute him (Richard)
Personally, I really enjoyed this act. I could actually understand what was going on and it was quite riveting. It would have been nice if the previous acts had been so easy to devour. I'm excited to see how this tragedy all comes to a close.
