Rey was starting to wonder if R2D2 had done something to himself to get attention. She knew he missed Anakin, but as she was studying what was wrong with the droid, she had to wonder if he felt like he was getting enough attention. She made a mental note to spend more time with Artoo.
At the voice, she looked up and offered a smile. She was learning that lots of people here seemed to know some of her world, though it seemed she was lesser known. She actually took some solace in that - having people know who she really was and what had happened to her, especially with her and Ben, was a lot to deal with.
"There are. This is R2D2 and this is BB-8." Both droids made some happy beeping noises that were maybe hellos.
