In response to a word challenge for 'Devotion'.
"Devotion notwithstanding, it's really got to stop," Merlin said, folding his arms, looking at his mentor with his head tipped slightly to one side.
Gaius, facing the mirror, looked eminently relieved, as he ran his finger tips over one eyebrow, smoothing the hair down. He scowled, turning to look at Merlin. "What do you mean devotion?!"
"To that brow!" Merlin shook his head, "If I didn't know any better, I'd say you had the thing consecrated as a weapon of offense. As it is I just know you're inordinately fond of it. That can be the only explanations for why you'd hex it in the first pace and look where it got you!"
"You mean look what you did with it."
"Who's always telling me to watch what it is I do with magic?"
"Don't throw my arguments back in my teeth!"
"Ohhh, so what's good for the goose doesn't apply to the gander..." Merlin nodded sagely.
Gaius just looked at him in disapproval, his eyebrow arced and raised.
Merlin grinned. "There, that's more like it. That's the look that get results."
Gaius just snorted in disdain, but turned to look in the mirror nonetheless.
