Eleven wanted to leave the report behind for Bai Ye and Su Man to carry on researching them. Following Old Witch's conditioning of her body, the virus in her body did not change much and would not mutate in at least the next two years. Two years would be more than enough for them to research it and possibly save Eleven by then.
Bai Ye happened to have a legitimate reason to remain in Riyadh, and Cheng Anya and Eleven talked about Su Man and Bai Ye. Eleven was taken aback for a long moment and then stupidly asked how they should be addressed in terms of seniority.
Everybody was taken aback. They did not understand why Eleven suddenly asked about seniority. Since they and Su Man were of the same generation, despite him being chum buddies with the young kid, he was just a year older than Bai Ye and about five to six years older than Eleven. They could be considered to be of the same generation.
