Travis also shows his immaturity when he gets into a fight with his little brother, Arliss. Travis is in that in-between age, where he's not an adult, but he's not a child either. Travis is a responsible young man, however, and he wants to prove to his father that he is a man. Travis is also a caring person who shows his sincerity about his feelings for Old Yeller. At the end, when Travis must shoot Old Yeller, he shows that he has become a man while his father has been gone. He has matured and does what has to be done, even though he doesn't want to do it.
