Dave examined the blackboard nervously. All the equations had made sense yesterday when he first used the calculations to switch bodies with Andrea. He wondered if it was an effect of the swap. Sure, Andrea was a smart woman, but she wasn’t anywhere near the level of genius he was. While he had his own thoughts and his own memories, he still had her body. That meant he had her brain chemistry and her neurological pathways. If they just weren’t firing at the levels he was used to, this sort of stuff might be well beyond his ability as long as he was in her body. Of course, he couldn’t get back to his own body unless he could make sense of these equations that switched them in the first place. His only hope was to enlist Andrea’s help to figure this all out. Surely if they worked together, they could decipher these complex mathematical formulas.
