Wait a damn minute Merlin is an actual nightmare of a servant. Imagine you're the Prince and all of a sudden and only two seconds after surviving an assassination attempt you're stuck with this scrawny, clumsy fucking dude with a really shifty air about him who spends literal days in the tavern with zero notice, steals your food, tried to spy on a guest, doesn't let you hunt, can never fucking be found when you need him even though he is the literal manservant to the prince, which you would think should be a priority but apparently he has better things to do, and is always talking like he's the only thing standing between you and certain death???? Then he gives you attitude? Literally I would throw things at him too. Arthur is misunderstood he's actually being too nice
