As for the scene in which Sakae Gozen believes that the children have been swapped, the original script of Ningyo Joruri 'Meiboku Sendai Hagi' says that it is because Komaki, who in fact supports the loyal retainers, has lied about it to Sakae Gozen, and on some occasions Komaki appears and discloses it before the curtain fall of 'Mansion' (for example, the performance in November 2004 at Shochiku-za Theater).
栄御前が取り替え子を信じるくだりについて、浄瑠璃「伽羅先代萩」原文には、本当は忠臣方に連なる小槙が栄御前に予め嘘を吹き込んでいた、という設定があり、「御殿」の幕切れに小槙が登場しそのことを告げる演出もある（平成16年〈2004年〉11月松竹座など）。
