Arcturus seemed so disheartened by the interactions through the network that Narcissa felt her heart go out to him. She withheld the need to reach out physically and hold his hand; she had always been one of physical comfort and support but she would need to get to know him better to do the same for him. Instead, she could just be there for him, talk through everything that might be upsetting him. "I'm sorry you had to discover it this way, in such a strange place without those closest to you present. I hope you'll come to see me as someone you can trust and come to if you ever feel upset about something." She took a cup from the house elf and handed it to him. "There are people, sadly some here, that are so self righteous that they don't think of others and how their words might impact them. I know that I am certainly not the most current of our world, but I would be happy to answer any questions you might have." She took her own cup, adding cream and sugar to it. Really, Lucius would be able to handle this conversation better than herself. But she was his support at the moment and she would do the best she could.
She didn't make a comment about his father coming to get him; she didn't know when it would be the appropriate time to try and tell him there was a good possibility they were stuck here. Aunt Cassi seemed to think there was a way to break the barrier, but Narcissa wasn't sure if she cared to pursue that option so much. Even though they may have been surrounded by all things muggles, it was peaceful. No war, no strife. Lucius was here and he loved her as much as he loved her from her own time. What more could she ask for?
"Perhaps we would be able to teach you some items," she said with a smile. "It would not be quite the same, but when you're able to go back home, you may be able to test and show that you can keep up with your studies so you won't be left behind." Besides, the thought of a Black being left behind at Hogwarts was preposterous! Arcturus seemed to have a good head on his shoulders, Narcissa had a feeling he would be a fast learner.
She was happy to see him smile and returned it, taking a sip of her tea. "I'm quite happy to have met you as well. So far everyone from the wizarding community has been lovely." She set her cup down, motioning for the house elf to get some plum pudding for her guest. "Although I do not think I know Mr. Summerby. He is a wizard as well? His name sounds familiar...you had mentioned him before?"
