Merlin tries to spend as much time as he can in bed, but eventually, he knows he must get up. Arthur, knowing that Merlin prefers learning to get out of bed on his own accord when he's in one of his stints, lets Merlin be after assuring that his willingness to give Merlin a helping hand.
"A helping hand," Merlin snorts. "You'll push me out of bed, more like."
And Arthur can't deny that.
He does, however, light every single candle in their bedroom before heading to the kitchen to make breakfast.
"Stay in bed too long and there won't be any more of your favorite, nice smelling candles."
"I'll just make you buy me more!" Merlin shouts after him.
"Doesn't mean I'll do it, even if you were to ask!"
Arthur knows he'd buy more candles, anyways
It doesn't take Merlin that much longer to get out of bed and join Arthur in the kitchen, Arthur giving him a grateful kiss on Merlin's way to making himself a cuppa.
