Mo Shangjun moved her toothbrush, feeling it affected her speaking, so she simply took out the toothbrush and said: "I've found out that Qin Xue and Qin Lian acted together. When Qin Lian arrived, there were two Red Flags left, but only Qin Lian took one. And they were just a bit behind us, which means Qin Xue didn't take the Red Flag because she knew we'd arrived first and didn't take the Red Flag either. Then she assumed we took Orange Flags based on the number, so she herself also..."
Mo Shangjun paused here, then continued: "She didn't take a Red Flag, giving Qin Lian the reason that she didn't sleep well in the Red Dorm."
These things, she got from inquiring Yan Gui and Duan Zimu.
Because she saw Qin Xue staring bizarrely at Ding Jing that time, Mo Shangjun had doubts, and Ding Jing's response contained a sense of "understanding Qin Xue's intentions," which Mo Shangjun found strange, so she asked Yan Gui to get closer to Qin Lian.
