I think it's to Deven and the kids. "The cells we generate" is like he's talking to Deven about the two sons they've made together and the "Please be aware that I am you" is like him talking to his three kids about how they all share the same cells, he is them and they are him in a way. The "Sorry for this space" part could be to all of them because he loves them all and he will protect all of them. It's really a beautiful song. Makes me wanna cry.
