Serif: no I'm trying to protect you and them! (His void form comes out and dodges and puts arms around a kid) (kid is crying in blood) now go I'll take care of this!
Kid: (crying)
Serif: get her to a hospital or something...

Gaster: (his eyes go black. Then one eye turns cyan, like sans' s eye, the other is red, like papyrus' eye)
N O-
(body goes into void form, and he lunges at serif)

Serif: gaster go! Now I'll take care of this! (This reminds you of sans vs frisk)

This is entertaining :^

Gaster: chara, this isn't you!
(Serif tries to attack her, but gaster takes the blow. He starts to bleed)
