When Ivy brought Rocky in, she entrusted you to take care of him as you are one of the people she trusted. You help carry Rocky to the spare room (Or borrow your room). Ivy left with very little explanation of when, how and why Rocky was injured. A rushed truth, shoving medicine and supplies to your arms and she left you with Rocky until she comes back later. You go and check on him, but he stood by you and spoke with a fainted, slow voice

"...hi."
