Teddy’s parents did a great job with him , but they were so much younger , and not dealing with seeing their son put his life together again and the changes that wrought in him. Seems the honesty they shared with Teddy , took a backseat with Oliver and now the consequences are coming due . Teddy is at least 13 years older than Oliver , went to Med School , did internships , residencies etc , where would he find the time , energy or inclination to be the perfect brother and best friend to Oliver? Despite all the water under the bridge , it seems Teddy , Ryder and Oliver may just be good for each other . I have a feeling too , that Mike is not merely a meaningless placeholder in the developing story .
