[Yokuutsu]

The rants aren't a product of a drunken mind. It's the product of a Yuki being pissed off. So he's just talking to the toddler version on himself...but not in English. He's speaking in Japanese since they both understand it.

As Niaz picks up the toddler him, the toddler starts completely flipping out...and it is obvious that Yuki's...internal organs just dropped. It triggers a certain memory he'd rather not remember, a certain nightmare...which for the moment he's able to keep at bay. "Let him go!" Even if Yuki is still a bit tipsy, he wasn't happy with Niaz....and now he's even less happy about this. "Put him down now!" It's okay, well...better, if Niaz fucks with him, but the other is a child and so should be left alone.
