Merlyn the Timelord and Arthur his Companion

"There is a thing about Time and Space
which the philosopher Einstein is going to find out.
Some people call it Destiny." Pg.286

I believe no other story we have read thus far has gone as in depth into the friendship and teachings of Merlyn and Arthur. Even when Arthur has become king he still looks to Merlyn for guidance, especially on page 247 when Arthur believes he knows why Might isn’t Right and how Might can be Right. In this scene I believe Arthur to going back to being a child and looking up to his tutor/teacher for guidance hoping he has the right answer. Merlyn not responding to this moment shows that he no longer wants Arthur to look for him for anything else because he won’t always be there, he only praises Arthur when he starts thinking for himself and doesn’t rely on Merlyn anymore. But I believe the real reason why Merlyn doesn’t look at Arthur during his speech is because Merlyn doesn’t actually know whether his teachings are right or not. He goes in time backwards but knows that any decision he makes can affect the future which he has already lived, which is why he keeps telling Arthur what happens just in case things don’t work out completely the way it’s supposed to. Merlyn knows any sort of mistake he make affects the future, he has to make sure the lessons he teaches Arthur are the right ones. Arthur’s big speech is the result of everything Merlyn has taught him and it seems like the beginning of Arthur’s legacy. It’s like The Doctor from Doctor Who letting go of his companions in the hopes that they will be better off without him and they will do greater things because they knew him.
