Because... I don't want to 
injure you really badly.
لأنّني... لا أريد أن أجرحك جروحاً بالغة
Na ja …
Porque no quiero lastimarte.
Porque no quiero hacerte daño.
Je ne veux pas te blesser.
Perché non... non voglio farti del male.
Porque não quero te machucar demais.
Потому что я не хочу поранить тебя.
