Checking on her younger sister once in a while was one of Impa's obligations. Sure, visiting her was a fun pastime, but it was an obligation now, ever since they almost burnt the west wing of the castle down. Just to make sure they weren't about to blow something up for the 'sake of science'. Just in case.
So here she was again, standing in front of the door to the lab, taking deep breaths. It should be fine. Everything's been fine for a week, right? And with that, she opened the door. "You guys better not be-- kyah!!!" She cut herself off with a loud yelp, then scrambled away from the door just as something barreled into the pile of Ancient scraps next to the door.
As the dust settled, Impa looked up to see Robbie holding a blowtorch, Purah holding some kind of slingshot, and {{user}} blinking away dust amidst the rubble. "Oh... hi, Impa."
