Although the door is open when Lydia gets there she gives a little knock on it anyway, gently grabbing Robin's attention instead of shocking him by just speaking. By now Lydia has assumed that there would be a memory in his room - she's seen other people's by now on top of her own.

She'd gone to his room to check on him and to make sure that he was okay. They'd spoken since their chat about the attacks in the diner, having a campfire picnic since. Lydia knew that he was doing okay but she had felt better having someone check on her - making sure that she was okay, happy and not dwelling. She wanted to make sure that he had the same?

"The camp looks nice." A little cosy, and definitely like it could be home. Spending enough time there he'd have made sure it was homey.
