Canto 2 -
Ayodhyā-kāṇḍa
Chapter 11: Kaikeyī Demands two Boons
Text 2.11.28

भरतो भजतामद्य यौवराज्यमकण्टकम्।
एष मे परमः कामो दत्तमेव वरं वृणे॥

bharato bhajatām adya yauvarājyam akaṇṭakam
eṣa me paramaḥ kāmo dattam eva varaṁ vṛṇe

bharataḥ = Bharata; bhajatām = may become; adya = today; yauvarājyam = the heir apparent; akaṇṭakam = with no obstacles; eṣaḥ = this; me = is my; paramaḥ = great; kāmaḥ = desire; dattam = that you have already bestowed upon me; eva = only; varam = for boons; vṛṇe = I am asking.

“May Bharata become the heir apparent today with no obstacles. This is my great desire. I am only asking you for boons that you have already bestowed upon me.

Kaikeyī’s statement that she only asked Daśaratha for boons that he had already bestowed upon her indicates that she did not ask for any new boon.
