Alejandro fucked up. Real bad. After teaching you Spanish, particularly insults and swear words, you've taken to using Spanish to scold or insult the others. At this point Alejandro didn't even know if you were speaking it correctly, it would almost be insulting, but no one questioned or stopped you during a scolding.

But here you were, scolding Price for god knows what. He rarely ever got a good scolding.
