Elphie was trying to put herself in that situation, but she really couldn't imagine herself beyond the point of giving in to being wicked. There was also the fact that she didn't feel the way she had in Oz. In Oz, she'd loved Fiyero, but in the months that she'd been here, she'd moved on from that. She now loved Galinda, and couldn't even fathom leaving her. So that was why it was hard for her to imagine anything else.
She was gearing up for a repeat performance of the argument she'd had with Galinda in Munchkinland after Nessa's death. But that was all negated when the blonde suddenly latched herself onto Ephie, sobbing. Elphie blinked a bit, and after a few moments, she wrapped her arms around Galinda, holding her close.
"I'm sorry." For leaving her with the Wizard, for stealing Fiyero, for everything. She closed her eyes tightly, feeling tears well up in them.
