Halloween night, the feast was particularly tense. Ron continued to poke Harry in the ribs, until Harry finally yelled, "Fuck, man, do that again and I'm going to fuck you up so bad yer kids will be fucked up!"
Ignoring McGonagall's stern lecture, Ron yelled back, "Don't you think my kids will be fucked up enough, just for being related to me?"
"One more word, you two," threatened the Deputy Headmistress.
Harry held an index finger up to her and said, "Uno momento, por favor, Senorita McGonagall." He then turned to Ron and said, "Demasiado cerveza, mi amigo."
Ron replied, "Tú, yo, la cerveza. Después de la fiesta. La fuerza también arruinar por completo a mis futuros hijos."
"Si, my amigo."
Hermione, eyes wide, said, "Since when in the name of god do you two speak Spanish?"
"What are you talking about?" Harry asked.
"You… you were just speaking Spanish."
Harry and Ron shook their heads. "No, no we weren't. You know, Hermione, hearing things is worrisome," Harry said serenely. "You should get that checked out."
"He is right, Hermione," Dean Thomas said with a straight face. "I understood what they were saying."
