The Doctor quickly caught her breath before she ran to Dexter. After giving the arm a few tugs she then took out her sonic screwdriver and quickly turned it on and scanned it over the hand before the hand finally let go of him. She then pressed the sonic into the palm of the plastic hand that caused the hand to stop moving. "It's all right, I've stopped it. There you go, you see?" She said quickly in reassurance before tossing him the arm."'Armless." She said with a small laugh.
