I choose this scene because the reader begins to understand Connor and how his past has shaped him, as a person. Connor takes the storked baby from the doorstep.
In this scene, Roland threatens Risa in the bathroom. Connor plays it "cool" as he is trying to disencourage. a fight. This is plays a key role in the storyline, as it solidifies the alliance between Risa and Connor.
Roland is eventually unwound, this is important as it erases one of the main characters of the novel. This also acts as an eye opener for the reader, as someone that they "know" is directly affected by unwinding.
