Just my take on COTV+Dust. Lore: Somehow The player wins against a Melty Sans of COTV Phase 3A causing the timeline to become extremely unstable making things like memories and entities to leak though and Sans unluckily gain memory of everything causing Him to lock himself in the true lab and wait for the Human to arrive for a final confrontation. Facts about ANU / A Nihilist's Ultimatum. #1: Sans only fight's cause he believes he has no other purpose than to fight. #2: Sans used the DT extractor on the Amalgamates instead of using it on the human so He can have some DT for His inevitable end. #3: Sans disregards Gaster for the previous plan failed and He doesn't believe in another that would. #4: His bad time eye only glows red due to His loss of patience and want to end it faster. #5: Sans killed no monsters other than the amalgamates.
