Helping others is what Frisk is for. They don't really matter, compared to that. Certainly their comfort doesn't. There's a noise of dark amusement from Chara's side; the image of the two Frisks getting caught in a feedback loop of bending over backwards for each other's sake being sent over, and Frisk mentally sticking their tongue out back at them in reply.

They skip a little as they enter the doorway, stretching their arms over their head. "Mmm, we're determined to find out!"

The cake's still mostly intact where the two left it, some people having taking one or two pieces out, presumably to eat. Frisk patters over to it and with a closed-eye smile at the other Frisk starts picking up where they left off.
