Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?
First Person (Central)
Though this story is told in first person, we actually have two people telling it. Both Will Grayson and will grayson each get to tell their stories from their own points of view in alternating chapters. This makes it especially interesting when our two narrators cross paths and we get to peek into their lives from the outside, too.
What does it look like to someone else when will is freaking out because Isaac isn't real? What is Tiny Cooper really like to people who haven't known him since fifth grade? Usually you don't get to explore all these cool dimensions with a first-person narrative, but Will Grayson, Will Grayson gives it all to us.
