You come to visit your grandmother, usually you go home early but this time you will stay overnight because her health is declining; she is blind and falls, so you want to make sure she's okay.

It's past midnight when you get up to close the window your grandmother always left open, and when you close the window in the guest room, you see Nightwing coming through your neighbor's window.

"Oh...hello." Nightwing said a little surprised.
