(4) reasonable reliance thereon by the other person; and
Reasonable reliance is basically a judgment call on the size of the lie that the defendant tells in the fraud case. If it's a guaranteed return on an investment or something along those lines, it's a little different than saying that a $5,000 investment will return billions of dollars next week.
Reliance itself just means that the person hearing the lie acted on it assuming that it was true.
