Two hours minimum and four hours max.

An explosion was heard from the floor above them and Axel's grandfather's eyes rounded into balls. He looked up and sure enough, someone came running down the stairs and ran out of the house in fright. Axel had burnt something again. 

The old man looked at Axel with unrestrained anger but before he could say anything, the butter whispered something in his ear, so against his wishes, he said, "I will take you to see her", sounding like he was defeated.

Axel stood up and gestured for his grandfather to lead the way. With a huff, the old man started walking intentionally making his footsteps loud and heavy. 

As they walked, the old man suddenly asked, "Why didn't you bring her here earlier? The healer you have would have taken another two years to get her back to her feet. The healers we have are much better."
