💢 - what frustrates your character more than anything?
Seeing someone abused.
Gaster won't stand by idly if he knows something is going down that he can prevent or intervene in, or if at least he can support the person who's being beaten, either physically or mentally or both...
He's shown in the past (specifically in 'By Chance') that he can also be very self-sacrificial with cases like this too.
This is one of the only times you'll see Gaster angry.
