"I can't protect you when you put yourself in danger
now, and you're always rushing in to try and help no
matter what I tell you. Destroying your body over and
over. Yet back there you managed to...Rescue your
friend without being injured or getting into a fight. I'm
so proud of you! From here on out I will devote myself
to training you. You're stuck with me."
