Leia heard R2D2 before she heard much of anything else. It was hard to miss the little clanking sounds he made when he walked. She liked the BB unit that Poe had, too. Much quieter, although his seemed to be far more talkative. And that was saying something.
She opened the door, offering a smile as she did. A part of her was still hesitant and wary about her father. It was hard not to be, considering. But she could tell how hard he was working to be different here. There was no Palpatine to corrupt him and as long as it stayed that way...maybe there was hope. And Leia was pretty big on hope.
"Hello, you two," she offered, opening the door a bit wider and letting them inside. "Come on in. This is a nice surprise." And honestly? It really was.
