小四 / Xiao Si

小四 is the abandoned infant whom Xiaodouzi finds near the well in [[FarewellMyConcubine|《霸王别姬》]], as summarized in 64.霸王别姬：疯魔与成活. Later, [[ChengDieyi|程蝶衣]] recognizes him and takes him as a student, extending the troupe line into a new era.

The episode reads Xiao Si as more than a passive product of historical pressure. He adopts new political language, challenges his teacher, seeks the Yu Ji role, and replaces Dieyi onstage. The host interprets this as active ambition and opportunism; his later reversal and punishment make him part of the same machinery of role seizure, denunciation, and ideological turn.
