Meta!Frisk has seen a lot of things since they left their own timeline. They’ve seen a lot of people influence other timelines in cruel ways, encouraging Frisks to kill everything around them. Normally, they’re numb to seeing the results. They’re numb to watching everyone in a universe slaughtered. They’ll even go as far as joining in with the voices, offering ways to make it be done and over with faster. They pondered if this made them worse, considering they could still recall how it used to bother them. Rarely though, they’ll become invested in something again. Something or someone. Their heart will leap to see them succeed, and shatter to see them cut down. They'll remember what it is not know the answer, and desperately wish they did. They'll remember what it is to hate the voices who try to sabotage them. Most of all, they would remember what it is to grieve.
( @flowey-answers is working on something awesome which they showed off in stream. Poor Meta!Frisk didn’t take seeing some of the results of it very well. )
