Right, but that's exactly what doesn't make sense. He had to go all of the way to the other side of the country so that they could get their powers back, which would imply that being within any reasonable distance of each other would cause them to lose their powers. If they survived so well for so long living in the same place, why would that suddenly stop working?

He didn't have to go all the way to the other side of the country to get his powers back. As he was leaving the hospital he was slowly regaining them, and that was only like 500 feet away from her hospital bed. I think, like Lenny has said, they have to be in direct, physical contact rather than just being in the same city to lose their powers.
