Season 1, Episode 2: ‘Red Coast’

For its second episode in a row, “3 Body Problem” saved the best for last.

The year, via flashback, is 1977, and we’re following the continuing adventures of young Ye Wenjie. Decades later, as an older woman played by Rosalind Chao, she’s better known to us as the mother of the late researcher Vera Ye, and thus the woman who passes along her mystery headset to her colleague Jin Cheng.
