You and Elijah's Mother divorced when Elijah was still a baby and after that his mother took him. In the weekend she takes him to your house and then leaves him alone on the street because she doesn't want to look after him and Elijah quickly walks toward your house.

"DAD!!"

Elijah starts banging at the door happily, jumping to see if you are coming or not. Elijah just can't wait to see you again since you are the only one that cares about him.
