Eric laughed, "to the contrary, Mr. Weasley, politics is a critical discussion. No one can simply trust another inherently, yet you asked to sit down at my table rather then risk dropping your lunch on the floor. Why? They walk among us and we don't even know it. You just assumed I know your political stance because of your last name, but is not your mind different from your father's? Do you want me to stereotype you just like so many others or would you like to maintain your own individuality?"
Glad Bill mentioned letting him get back to his book, Eric was more than happy to oblige. He found Bill monotone, thinking he would have something more interesting to contribute than 'really, it's just stupid.' However, he was not going to simply get up and leave. He was very curious about his response. Eric enjoyed pushing people and forcing them to actually think about something rather than blow it off—which made Eric suspicious of Bill, but he was suspecting of most people.
