I cannot even begin to articulate how beautiful and heartbreaking the Kevin moment was.
The idea that this man who Chimney loved as a brother, who he lost too soon, came back to him in his moment of need and pointed him home? The way Kevin is one of his ghosts, but only in the most loving way.
As tragic as it was, losing Kevin brought with it a realization of unconditional love in the Lees—because not only did they manage to love him through the hurt, but they needed him, too. He wasn't a reminder of their pain—he was the son they had left who they could have lost, too, but didn't. He was love and joy, even through all the hurt. They were a family. A little bit broken, but built on the kind of foundation Chimney had never had until them, at least not since he'd lost his mom.
For Kevin to be the one to point him home? To send him to the two people whose unconditional love had kept him alive, if only in their hearts? To the parents who'd raised them both and didn't deserve to lose another son? To the two people who had never let him down?
