It tells Four POV as he train The new initiates, includeing Tris.
I do not know why this is the specific scene that was chosen to share Four's thoughts. A lot of scenes come to my mind that I would like to hear what Four's thinking was. But anyways, I'm still thankful to read a bit of him. Four is in top of my list of the most drool-worthy leading men.
It's nice to finally hear how he feels for Tris even from the start. But I think, this have given me a clearer perspective of Eric. What he's capable of and how evil he is.
I just hope there's more!
