I liked this chapter! Stupid slut, but at least she knew he wasn't cheating. I did catch some errors though.
In the paragraph where he's explaining how he did the math problem: Well we wanted to find the value of x. The system you gave me was five equals two x squared minus nine x. We subtract five from each side to get zero equals two x squared minus nine x minus five. Then we plug it into the quadratic formula to get nine plus or minus the square root of nine squared minus four times twi times five. I think you meant two, right?
I say, starting to read them outloud and explain them in simple terms. Just need to space between out loud.
"We know eachother too well. I knew you were going to show up eventually..." Just need a space.
