[ She wants it to be a lie, wants Kokichi to say he was just kidding and that they all escaped right after she died.

Yet at the same time, she knows for sure that things wouldn't be that easy after she left. ]

It could be, but I don't think it is. I don't think even you would lie about this.

[ Maybe she just has too much faith in other people to think Kokichi would be telling the truth, or maybe it's because she doesn't know what he ended up doing later on.

Regardless, she believes him. ]

And if you are lying... I'll be pretty mad.
