Don't treat him like a clone. Treat him like a young man who is just having problems. But if everyone treats him like a clone then he's going to have identity issues and we don't want him to have anything like that. Not when he already has memories that aren't his own.
If anything? We should take a note out of Jordan Kent's book and treat him like family. Like he's just another kid because in the end, he is just another kid.
