Yi's younger sister, though she didn't take to science in the same way Yi did, she was always curious. Heng was born with the ability to communicate directly with the roots, which she told Yi, though he brushsed it off as her making things up. Heng was closer with their parents due to her sticking closer to their tradition and spiritual beliefs despite often spending time with Yi.

Line Context and Tone:

Line 1: Heng and Yi are on a ride past the broken Rhizomatic Columns where Heng wants to learn about them from Yi. Yi tells her that she should of learned about them in school, to which she responds with this stubbornly. 

Line 2: Heng and Yi are talking about the roots, and this is where Heng brings up being able to hear the roots for the first time. Though Yi tells her she's making this up, she poetically explains how she believes the roots work due to her ability to hear them "sing". 

Line 3: Heng finds Yi hiding away in a pickling jar reading scientific books. Growing up in a traditional family on Xia, there is a lot of prejudice against science. Heng is telling Yi off for reading the science books but still wants to spend time with him.
