Oh, I just realized why you 
hold such animosity toward me.
لقد عرفت! عرفتُ سبب عدائيّتك هذه تجاهي

Sé por qué me guardas tanto rencor.
¿Eh? Ya lo he descubierto.
Sé por qué me guardas tanto rencor.
Je crois que j’ai compris

Ué? Entendi. Entendi por que 
tem esse rancor todo contra mim.
О, я понял, почему
