His chest felt empty as she didn't say anything to begin with, and then his stomach did as she spoke without emotion. He stood uselessly across from her, his brow aching as he tried not to let them raise or furrow, his gaze flickering away from her eyes to avoid the shame, but flickering back moments later to face it.
Robbie swallowed as her fury rose, and his mind raced about what he could explain to her. He couldn't tell her about Zacharias, he believed in the Ministry too much to ever give up that information, and if it meant Alicia would hate him forever, he'd have to deal with that. It was the reason he'd done the Obliviation in the first place; it was too important. "It was important, it still is," he explained, possibly obviously stalling as he cast his gaze around the room, before meeting hers. "That terrorist group, the one blowing up the Ministry and assassinating people, it's to do with that," he explained, somewhat emphatically. "It protects people, innocent people's lives."
"And I really didn't know I'd hurt her. I've done it hundreds of times before, it was my job. I've never had it go wrong before. I still don't know how it did." He sighed in frustration. He shouldn't have even been trying to defend himself, but he needed to say it, in the faintest hope that she might... not forgive him, but understand a little better.
At her question, his brow did raise then. "No!" he said immediately; his honest, gut reaction, and then half-turned away as he dragged his hand down his face. "I trust you, I wouldn't have needed to." His eyes burned as he blinked, was he going to bloody cry? The thought of erasing her memory of himself touched a nerve; it was erasing a friendship, and though Alicia wasn't the best friend he'd had in Cedric, no one was, she was close, and it hurt to think about losing another person.
