What this is is a replay of what's recorded in his journal. You've probably heard "In medias res" at least once in your life, and it's a term to describe the narration of a story from the middle of the plot, instead of the conventional beginning. A good example is the setup of Final Fantasy X, how Tidus explains everything from the middle of the game in Zanarkand ruins, instead of just following him as he progresses.
What you're looking at here is the records Mattie has kept in his journal. They - the records - will lead up to the couple of pages I've previously uploaded and the story will continue on from there.
Oh, and just so you know - every article of Mattie's designer wardrobe is capable of making expressions. The sweater vest and tie was given to him by Leon, since Mattie doesn't have any real "formal" clothing.
Sorry if this was super confusing or soemthing e_e;;; Apparently everyone got confused.
Thanks for the clarification.
I'm familiar with that style of story-telling, but I guess I should have just waited a bit longer for things to play out and make a little more sense.
Also, I like the way you are drawing your characters now than you did before. Keep up the good work! :)
