This event isn't a battle, but it had a major role during the events of Season 2's beggining. Counting Asriel's few attacks against Bete, it can be considered a battle, of some sort. This event implied Sans, Asriel, Bete Noire and Jessica Grey.


After the HSO meeting incident, Jessica Grey, the AMD director was blinded with the wish of revenge, she decided to be an ally of the Bete Noire.

Bete Noire's purpose is to make sure that monsters, and humans would never live in peace.

Asriel and Sans were looking for some proof. They were searching at AMD's security camera room to find some information after Sans argued with Frisk.


After Sans "blamed" Frisk about their empty promise, he decided to go to the AMD security room with Asriel.

They started to slowly discovering the camera's files that Bete was implied during many "weird" things (Bete teleporting outside, the illusions).

However, she was about to just make a surprise for them by entering the room. Sans and Asriel tried to flee but Jessica (who was hiding in a dark corner) shot Sans with the AMR While he was neutralized, Bete tried to assassinate Asriel by mentally manipulating him (The illusion of him seeing Chara instead of Bete).

Again, however, Sans found the Determination to teleport in front of Asriel and take the hit. Bete led the soul into Akumu's mouth, causing Sans to turn into Dust. Then Asriel left by breaking the wall. 

As Sans turned to dust and Asriel retreated, Bete ordered Jessica to give the HATE Vial she would later possess in "Love Part 1". Jessica refused and Bete tortured her to relive her worst nightmares until they took the HATE vial. This left mental wounds on Jessica.
