I took one of George's hands out of storage and held it at the end of George's wrist.
"Is this the right hand?" I said, absentmindedly thinking aloud. "No, this is the left hand, which is right, as in correct."
George was still pale faced and he watched me so nervously.
"Don't worry. I'll make sure I put you back together correctly." I continued, feeling pretty bad for the guy. George closed his eyes and let out a long sigh of pent up anxiety.
As I healed his hand at the area where it was severed, I influenced his magic to go back into the severed hand. After fiddling with it for a moment, George's inherent magic seemed to recognize the hand as his. Then, my restoration magic started working as normal. From there, it healed rapidly.
