It's Pete being autobiographical:
He sees Elvis as a young lad. Thinks Elvis is a RGLB.
Later he sees his own image in the mirror. Thinks he's a RGLB, too!
His mother tells him he's an ugly boy; says he doesn't look anything like Elvis. Weird genes.
However, he (Pete) eventually survives to find love. He's told he's beautiful as he is. He has found peace.
God gave Elvis a face & God gave Pete a grace. Once again, he feels he truly is a RGLB.
