The real Silas—my Silas, my brain prompts me, which is a weird way of looking at it but not technically untrue—is so much brighter than the old version. He smiles more: still small, shy smiles that are mostly for me, but they’re so genuine. He laughs and talks more easily with me and the open, unguarded way he gives affection to Maddi and Sky makes me want to beam at him and never stop.
