With Shion avoiding him, Rei starts wondering if he's been dumped. Rei and Jin have a heart-to-heart talk about relationships. Jin points out that Rei has changed a lot. Jin convinces Rei to run after Shion and try to salvage things before it's too late.
But if you don't want to open up 
to me, how could I possibly ask?
Aber wie hätte ich danach fragen sollen,
wenn du mir nichts anvertraust?
Pero, si no te abres,
¿cómo iba a preguntar nada?
Par contre,
Ma... se non volevi parlarmene,
Mas se você não quer se abrir comigo,
como eu poderia perguntar?
