How do Obstinate and Faithful show the traits they are names for and how do they affect Christian's journey in the allegory of the pilgrims progress

Obstinate, like Pliable and Vanity Fair, display negative connotations, of their meanings while Faithful, like Help and Hopeful, diplay positive meanings of their word. Obstinate is of the first men that Christian encounters as he leaves on his pilgrimage. Obstinate eventually refuses to accompany Christian on his journey, and later publicly mocks him for leaving. Faithful is Christian's first companion on the pilgrimage. They meet up after Christian passes through the Valley of the Shadow of Death, and the two share enlightening conversation. Faithful becomes a martyr at Vanity-Fair, where he is burnt at the stake on trumped up charges of inciting a riot. Faithful's testimony, comportment, and noble death inspire Hopeful to undertake the pilgrimage, and he becomes Christian's next companion.
