I have this image in my head where, when Chall does his thing, magical energy races through town and wraps around Wren's body doing. . .Whatever you want it to do. But this is a timing thing. The boy would get to Marge with just enough time for her to follow him back, and watch him tap the line, then she would notice the magic, connect the dots, and then insist Chall come back with her. BUT, because I didn't wanna control the whole happening, and I don't quite have Marge settled into my head, I thought I would stop where I did to give us a chance to talk, and if you want me to add a bit or wanna change the undertone altogether, we can do that with only a little shifting. It's up to you.
