Yea. I don't want him to be OP so I don't want him to be stronger, but he will have more control ove this powers. Like before he couldn't tap into all his strength, and his emotional state dictated how his teleporting abilities worked, and his black matter was a lot more volatile than strong. 
And his split personality will be interesting to handle. Like it will only really flare up around phantom, and when his blood gets boiling for battle. Sometimes when he is angry. Kieran is suppose to be his actual like dark side.
