He is the oldest, 16 year old, brother of the Kanes. He has two younger brothers: Callahan, who is 13 at that time and Rowan, who is 10. Callahans irresponsible behaviour annoys him often. He cares for them since their mother died not too long ago and their father Seth became an alcoholic and abusive man. He hurts Declan, but Declan doesn't want anyone else to know. He just wants to protect his brothers from their father. The only one they can turn to is their grandfather Brady.
