What she witnessed after looking up was Lan with teary eyes, Colinde with impressed eyes and finally Rein with kind eyes. Both Mei and Himiko were expressionless for the most part but still one was able to see a little bit of worry in their eyes. Lu Shi's circumstances were just too bad and the way she was still able to get back up was just amazing.
According to Rein's values Lu Shi's intention for revenge was justified. But still killing off a whole city was way too extreme and Rein wanted to find a different way she would be able to take revenge on the people who were responsible for her hardships.
So Rein spent some alone time with Lu Shi and had a very long conversation with her. He wanted to know more about her and at the same time he wanted her to know more about him, Colinde and Lan too. Rein first calmed her down from her emotional state which was actually a simple thing to do as Lu Shi without a doubt was very nature emotionally.
