Note to King Lear, 1.5.24: "I did her wrong"

Who is King Lear thinking about?

Why it could be Goneril: The Fool has just been making comments which point to what the audience already knows to be true, which is that Lear will get the same treatment from Regan as he has had from Goneril. This contradicts Lear's idea, expressed in the heat of his rage against Goneril, that Regan will welcome him and all of his 100 knights. So, perhaps something of what the Fool has been saying has sunk in far enough that Lear is having second thoughts about what he said about Goneril.

Why it could be Cordelia: In the previous scene Lear's anger against Goneril led him to compare his emotional state to what he felt about Cordelia when she refused to join in the "I-love-Daddy-the-most" game. At that moment he said that her "small fault" bent him out of shape and turned his love for Cordelia into gall. Is it possible that now, faced with the prospect that Regan will be just as hateful as Goneril, Lear is again thinking that he did Cordelia wrong?
