Charlie asked. “Chimera Mark Five? Defense mode? Access code? What?” “Mark Five,” mused Maria. “Like Iron Man and his suits! I wonder if that means there’s a version four out there somewhere? And a three?” Charlie didn’t know much about Iron Man, but she too wondered why the bracelet would be called a Mark Five. “Yeah—maybe it’s like how new versions of phones and programs are named. Like iPhone 7 or Windows 10.” “So, you think there might be other bracelets out there?” asked Maria, eyes widening. Charlie thought about it. “Don’t people just get rid of their old phones when they get an upgrade?” Maria shrugged. “I guess.” “Hmm.” Mac had been studying the phrases as they flashed across the bracelet’s screen, and while the girls discussed the meaning of Mark Five, he turned to his tablet, typed “Chimera Mark Five,” and hit Enter, then sat back and frowned as the search engine produced no results. “Nothing? Seriously?” He shrugged and deleted the last two words, then hit Enter again.
