>>11164050When Tidus got caught by the Al Bhed and went "Wait, you can understand me?!" when he realized that Rikku can speak his language, she said that it was just like her and Kiara, with Noel being unable to speak English and Kiara being able to speak both JP and EN.
It's probably not exactly what she said but that's the general idea, still working on my JP reps and I'm watching the Council Collab at the same time.
