As soon as the words leave Ginko's mouth, Klaus has made up his mind. He doesn't know terribly much about him as an individual, but he does know that Ginko is a caretaker, not to mention someone who has a pretty full load to deal with. There is no way that Klaus is going to let anyone literally work himself into the ground.

He straightens up, perhaps a little too quickly for someone of his stature. The wooziness induced by the fact that inertia isn't strong enough to move his blood and his head at the same speed only lasts a brief moment, but it's just enough to send him toppling into the grave, his landing punctuated by the dreadful sound of wood buckling.

Great job, Klaus. Now you're the one who's literally in the ground.
