He will more than likely be back and at first be very cautious but since he didnt see you and nothing happened he will calm down. Deer are an animal of habit and since hes been around awhile he will come back. Try to be more careful about crossing their runs unless you have no choice then try to eliminate your scent. My favorite scent cover is wood smoke as it is a natural scent to deer and doesnt spook em. I hope this helps.
