For the father's part, the son brought him to the point of being able to commit to relationships which he had not previously been able to do with his partner. The grief the father suffered after learning his partner had been mortally wounded and then died after a brutal gay bashing scene resulted in a very touching bonding scene between the father and son. The father grew into and fully accepted his father role and the son was grateful to finally have the father who had been missing in his life.
