Dave realized he wasn’t about to get any help from Andrea any time soon. If she was able to figure it out, she either wasn’t cooperating or refused to accept the fact that she now had his ability. Regardless, he was back to his own devices on this. He coped all the information from the chalkboard into a notebook and brought it home. He didn’t expect a revelation to come to him, but he couldn’t just give up either. He was prepared to run over these equations until his brain hurt. He needed to get back to his own body, and figuring out the math was the only way how. Maybe he just needed to apply himself a little bit more than he was used to. He ended up staying awake all night, but was still nowhere closer to a solution than the had been yesterday.
