Trio VS. Gellert
Ron stood on the porch with Harry and Hermione. He was glad Harry had invited him. This was their opportunity to catch Grindelwald doing something bad, though he had no idea what would happen if they actually found something.
His eyes slid over to Hermione. He wanted to say something to her, but he knew now wasn't the time. He was here for Harry, and the Watch. Ron looked over at Harry and flashed him a little smirk before knocking on the door, and trying his best to look like they weren't going to snoop around when given the chance.
