I made some changes in this chapter (I added a few words that I had forgotten in Bill’s speech, as well as some modifications to the interaction between Mabel and Pacifica).
I find it doubtful Bill didn't catch onto the Dipper pines part, since he himself first called MC "Not-Dipper". So him saying Bill can do anything anything with "Dipper Pines" is worthless and Bill can't NOT know about it
