The fact is Ash was 100% going to run and make his way to that airport. He was going to go, even though he specifically said he’d never meet him again, but when he saw that plane ticket in the envelope he threw away all rhyme or reason and only thought of one thing: being filled with the endless warmth and happiness Eiji gave him and promised he could have in Japan.

Bonus: When Ibe was booking the flights, Eiji specifically asked him to make sure Ash be seated next to him.
