Father always encouraged me to learn, so I am the last person who is going to call you a glutton for punishment when it comes to that. Besides, if you hadn't stayed with the the whole magic thing, then we wouldn't have met.

[Not for the 'first' time and probably not for the second either. Who knows why they were each flagged to be the survivors of their world, but if Waver Velvet had been a completely different person, would it have still been him? And even if it had been, why would he have bothered to help Diarmuid who would have been a complete stranger then as opposed to an alternate version of someone who meant a great deal to him?]

Though, if you hadn't stayed to be a magus, do you think you still would be teaching something somewhere?
