All his close friends and enemies in Alexander's personal life were based or settled in Italy, Greece, France, California and New York. If any of them had Hera, then she should be somewhere in these places. Alexander never stopped looking into hospitals.

If there was any chance of Johnathan having Hera, Alexander could only thank his luck that Johnathan never brought her to his hometown.
