Nuance of "わね”: whose interest does「興味深いわね」refer to?


I have a question about the nuance of わね in the below song lyric (from
[衛星カフェテラス](https://www.youtube.com/watch?v=HpFSeGMMafU)):

> あのさ、もし意識思考そのものが自律して

> この体を逃れたなら (意識は自律して? 興味深いわね)

I was thinking that this was implying that the matter being 'deep' was being
felt by the speaker, as in:

> That's really deep!

However there is a doubt as to whether this actually refers to the speaker
talking about the other person's interest (who she is singing together with),
as in:

> You’re really interested in that, huh?

Whose 'interest' is being referred to in this phrase?




This 興味深いわね is just "That's interesting" or more specifically, "This
'意識思考そのものが自律して...' is an interesting assumption." わね is a feminine sentence-
end particle which does not necessarily have to be translated, but it's for
seeking agreement; "huh?" or "isn't it?"

興味深い never means someone is interested. For example, 彼は興味深い always means "He
is an interesting person" rather than "He is interested (in something)."
彼は(～に)興味がある and 彼は(～に)興味を持っている are the expressions that mean "He is interested
(in ～)."

  * 興味深いわね。 That (such an assumption) is interesting.
  * 興味があるわね。 I am interested in that.
  * 興味があるのね。 So you're interested in that.
