>Chapter 1: Tells you to check the book upstairs, repeating his dialog removes the upstairs mention
Chapter 2: Second floor accessible, Normal NPC moves slightly to the left in each visit to let you read a book
>Chapter 4: "I love reading. Especially... wait. Wait. The books upstairs. The books upstairs. Wait. The books are...... Wait. Wait, love."
>Can be found interrupting the spot to meet Onion on the lake
Book upstairs = Next Chapter = Literal next page from Gerson's inspired book.

Normal NPC is a monster brainwashed by Gaster for giving hints to the Player. The Weird Route is the path to break the prophecy, leading to L.O.V.E. Onion is a character that wants to find out the song from the sea, leading to Gaster. Suddenly Normal NPC stops your path to meet Onion. What a coincidence.
