I've seen a lot of stories going around where they're just little drabbles. So I guess this is my first attempt at one.
Suspect
He thinks he's known for a while. He wasn't as stupid as he looked, despite popular belief. He'd seen enough tree branches falling on bandits, mercenaries right when he needed it. He'd seen more then enough weapons suddenly finding themselves very, very hot. Hell, he'd seen plates come flying out of nowhere. In each and everyone of those situations, Merlin had been present and accounted for.
In fact, Gwaine couldn't remember a time when Merlin wasn't there, right beside them whether it be hunting trip, dangerous quest, army of immortal soldiers taking over Camelot, Morgana controlling said immortal army or the aftermath of a drink to many at some feast, tavern what have you.
In other words, Merlin had been there pretty much every single time that magic could have been used to overcome whatever hurdle Arthur seemed to face on a weekly basis.
In conclusion, Sir Gwaine, Knight of Camelot believed that his best and probably closest friend had magic. The only problem would be confronting him about it.
Please review.
