[Can't step around this. Chara's asking a question, and Frisk doesn't know the answer. Go ahead, Frisk. Pass judgment on a relationship you're only vaguely familiar with, vicariously, via the same, repeated day you shared thanks to Chara lingering in your head, feeding certain memories to you but withholding others in an ebb and flow that may have been entirely unintentional, and do so in a way that doesn't end up hurting Chara or contradicting anything Asriel may or may not have said.

Simple, right?

Frisk winces under the pressure of an abrupt and unanticipated spike of sympathy for Sans.]

I...I don't know, Chara. I don't know. I don't wanna say that you should - you should make everything you are rest on someone else. Be dependent on their living to keep living too. But -

[Ha-ha, but. Aren't they exactly the same way? Aren't they both of them guilty of just that?]

I don't know if we'd be happier without that. If we'd be better. I know I don't want that, and I don't think he'd want that either, but I don't - I don't know. I don't know him like I know you.

[And even then, they don't always feel like they know Chara very well at all.]
