It's going back full circle. That in itself was the part that got me thinking how the plot was moving to lurk back into the beginning to end this misery. This got me through a dreadful experience that was very traumatizing. As a matter of fact, the incident took up a lot of chapters due to its detailed account of how the characters pulled through to come to a decision that was air-tight with a solid alibi. I didn't know what to expect after, but the end brought me both tears of joy and agony, though the former was overpowering.
