"And Orwell's hell, a terror era coming true. But this little brother's watching you too." This is a reference to the classic George Orwell novel 1984
, where the state is basically this unseen authoritarian force that controls everything and everybody. The term Orwell uses for the government is "Big Brother" (which is still used as a metaphor for government over 50 years after he wrote the book in 1948). So "little brother" in that lyric would be the average citizen, who's aware of the government's abuse/authority and knows it's wrong.
