Luke. Always ready with a grin and a joke. Dark hair and blue eyes. Knows he's cute and uses it to his advantage. Beneath all that, he's a deeply perceptive, caring kind of guy. And he has a knack for seeing exactly what Grace is trying to hide.
this actually made me cry. isaac was always in pain, and never had anyone there for him to help take away his pain. and he takes just a little bit of the dog's pain away. its just a super meaningful scene. <3 isaac.
