Maybe it's Arwen!

You... are aware that there have been a number of unfortunate events related to the puppeteer, right? No one knows how these monsters are being controlled by a central power. Everything around here needs to be scrutinized and suspected. Come to think of it... don't you think 妖精 艾溫 is a tad bit suspicious as well?

Arwen seems strange! Otherwise, how else can you explain the fact that she always losing her glass shoes? A fairy who loves forest, and she's standing in 勇士之村! I think she's just doing that to disturb the great people of Maple. Maybe she's being controlled by the Puppeteer! We need to look into this!

There's one way we can tell whether Arwen is controlled or not: 清澈的樹脂, which can only be purchased at 大木林之巔... For an innocent Fairy, it works as a potent medicine, but for a devious character, it turns into a poison. Can you give that to Arwen for me?

If Arwen comes out unscathed from this.. Then great. If not... hahaha... like I said, everything that seems remotely suspicious must be investigated.

What? You don't want to do this with me? How can you say that? If Arwen winds up working for Black Mage, then will you take the full responsibility for this?

What is it? I am not fond of humans... wait, is that 清澈的樹脂? Is that for me? I can't believe there's a human being out there that is sensitive enough to offer me something as great as this. I knew my beauty would work in the human world, as well.

Thank you. This will make my skin look 10 years younger. Yay!

(Arwen seems unaffected by it. Too unaffected.)

What does a human need from me? Are you here to give me the glass shoes?

Haven't you gone to see Arwen yet? I thought I told you to find 清澈的樹脂 at 大木林之巔, and give her the medicine.
