After pondering and digesting some information, Emilio managed to conclude a few things.
First, neither his current parents nor the other 'Emilio' seemed to know who Ariana or Alison's family were. When Emilio mentioned Alison's name at one point, both Melisa and Alister immediately showed their confused faces. Emilio has learned a lot from his past life. Emilio could already tell when his mother was trying to lie to him. But this time, both of them were confused. They had no idea who Alison's family was or why their son was suddenly asking about that family.
Secondly, neither of them knew King Alexius or Raoul. Even though King Alexius was supposed to be a good friend of his parents, in this new world, neither King Alexius nor Raoul seemed to exist. This second point was the most worrying for Emilio. Since Emilio had so far only found people who had died in his previous life, the teenager was afraid that this world would not have a living Ariana.
