when Glouster finds the king,how does he react to the company he is keeping and to the king's mental condition?

In Act III, Scene IV, Gloucester questions the King's company before remarking that he and Lear must both hate what their bodies have given birth to, namely Edgar, Regan, and Goneril. Although he has been barred from securing shelter in his own castle for Lear, Gloucester entreats the King to come with him to a better shelter. Lear wishes to stay and talk with Tom, terming him a philosopher. Kent urges Gloucester to plead with Lear to go, but Gloucester notes it is no surprise that Lear's wits are not about him when his own daughters seek his death. Lear is persuaded to follow Gloucester when they agree to allow Tom to accompany him.
