Dino, Veldora, Carrion, Hakuro, Souei, Sans, Alphys, Frisk, Asgore, and Monster Kid are all dead thanks to Betty.

Rimuru: was pissed but new he wasn’t anywhere near strong enough to kill Betty

Papyrus was crying from Sans death, Shion and Shuna were hugging him to cheat him up

Milim was clinging to Frey and Frey was cling to her. Both scared to lose each other

Benimaru: was training

Luminous was keeping Hinata close to her. Afraid to lose her but not showing it. Hinata didn’t mind

Diablo and Undyne: were sparing

Gaster and Gabiru: doing science

Gobta: holding onto Hakuro’s sword. Holding back tears

Toriel, Chara, and Asriel: we’re all injured from the last encounter and we’re healing
