- yup, Merlin is the Merlin. And definitely a wizard.
- he poisoned Morgana (who was not evil at this point in time) because she was the source of a spell threatening Camelot
- he also released the dragon, even though he suspected that it would go rampaging because he'd made a promise
- he's killed a number of people to protect Arthur
- Guess who has Iniss? Merlin does!
