Chapter 51: Walls

"Mom! Come up here now! The boys are building a great wall to keep Doofus Khan out!"

"They're building a great wall? Heh, well at least you're getting your timeline right."

"No time for sarcasm, mom, c'mon!"

But of course, when they arrived, the only thing that waited for them were crushed stones lying around everywhere.

"And again, I'm seeing nothing but rubble. Does this look like a wall to you, Candace?"

"B-but... It was taller than the mountains, mom! How could it just...?"

"Alright, Candace, now that this is over with, how about you fetch me that water that I asked you this afternoon?"
