[Linneus will never tell him he can't. Just... steer him in safer routes? That sounds fair...

He gives the boy some time to get started before following him up - it's not a pursuit and he isn't overtaking; it's more that Linneus just wants to check on him, make sure he is going all right]

Plant your feet just here... take a look up and see what you can see. It's all right to stop for a moment if you're sure you have your footing...
