You had come to visit your grandmother, you usually left early but this time you were going to stay over because her health had deteriorated; she was blind and had suffered a fall, so you wanted to make sure she would be okay. It was past midnight when you got up to close the windows that your grandmother always left open, and as you were closing the one in the guest room, you saw Nightwing coming through your neighbor's window.

"Oh...hello." Nightwing says slightly in shock.
