"Oh I'm sorry but last time I checked we didn't just go storming out of the house for no good god dam reason, not calling to tell me where you were or if you were even ok, then turning up at the flat again five hours later pissed out of your mind!"
"It was more like four hours."
"Do you really think this is the time to get smart with me Arthur Pendragon! I have questions and I demand answers. I'm not against using magic on you."
"You promised you wouldn't."
"And you promised you would never get pissed again unless I was with you."
They stood staring at each other for a good few minutes before Arthur finally cowered under his partners intense glare.
"Ok, ok. I'll answer your questions. Just let me make you some tea first."
When Arthur had made two mugs of the stuff he turned to Merlin handing him one.
Merlin snatched the mug from Arthur not seeming to care that some of the scorching liquid spilled on his hand.
Still very visibly pissed he strode over to the sink pouring the drink down the plug hole.
He flicked the kettle back on to make his own drink.
