LAKE POINT: It's Mikey

Outside in the hallway stood his 10-year old brother Mikey. As always, he was wearing one of his T-shirts, a pair of dirty jeans, and a pair of dirty sneakers. He must have been outside playing baseball with his friends, or something. "Oh. Hi, Mikey." As soon as he said that, though, the bracelet began to grow warm on his wrist. He glanced down and saw that the bracelet was also glowing, or more specifically the *glyphs* on the bracelet were glowing. Why was it doing that?
