Talk:Eternal Sonata/Chapter 6: Tristesse

I'm not sure if this is the right place for this but I'm confused at this point. The guide says to use the west portal first but it's not active on my game. Apparently I'm suppose to go there to fight Fugue but I can't. Is this a glitch or something only available on the encore play through? For now I suppose I'll just have to assume it's the latter and keep going since I'm not sure how long it'll take for a reply.
