"They don't realize it, but they shouldn't drink any more. They'll be sick." Why he has alcohol this time? Cole's the metaphorical designated driver.

"The chocolate was ignored. One of the animals tried to eat it." And animals + chocolate = vomiting for days.

But that doesn't really matter right now, does it. Because 9S is hurting, the thoughts of 2B continue in his head, she's not fine, she's infected, I can't do anything. It was bad to let these thoughts fester foul. People made terrible decisions. "You should talk about it," Cole says, almost out of nowhere, as he regards 9S with that creepy stare of his.
