Act 2 scene 2
The Queen, the only honerable character to see Richard in a good light in the play, here talks about how she can pretend happiness even when she is sad (unlike Bolingbroke who claimed he could not). But again like many of Shakespeare's wives she has premonitions of sorrow, which the play itself does not disprove. So though Shakespeare never comes out on the side of astrology (our fate is in our stars), he also never comes out against it; noone has premonitions that are not proved true.
York is torn between his loyalty to Richard because he has sworn allegiance to the King, and his loyalty to Bolingbroke whom he believes Richard has wronged. Yet because he was left in charge of England while Richard was in Ireland, he feels the obligation to fight Bolingbroke.
Bushy, Bagot, and Green can tell which way the political winds blow and are fearful because of their closeness to Richard. When Bagot says, "We three here part that ne'er shall meet again," he is prophetic.
