Pete offered hospitality until Donald finds his way. He also expresses his concern about what can happen to Donald in that long trip, so Pete comes and pick him up. Also Pete gave some money to Donald so he can support himself for a while.
On the other hand, Donald is worry about Pete’s view from life. Donald tries to convince him that money is not everything in life.

After their discussion Pete left Donald at the edge of the dark and lonely road. After while Pete decided to come back and pick him up again.
