It was no surprise to Arthur that Merlin flung himself at him like he did, though he easily returned the embrace, his own arms finding their way around the other's lanky build with a smile of his own. "I'm sorry," he murmured, his tone just barely loud enough for him to hear.
"Yes, I am," he said, his smile never fading even after they pulled away from each other. It felt so strange, though, actually seeing and talking to him in person. "Merlin..." the word trailed off as he gazed at him, still in awe and slight disbelief that he had magic all this time, right under his nose.
