okay…
I’m kinda confused now…
thnx.
Yeah I always got confused about whether it was Remy’s conscience or Gusteau’s ghost.
On the one hand, it could be Remy’s conscience because Gusteau never met Remy in person, and after he died, why would his spirit talk to Remy if he never knew about him?
On the other hand, it couldn’t be Remy’s conscience, because how could his conscience scare him when he was deciding whether he should escape or fix the soup?
bright dot-dasher - In response to your second comment/spoiler:
I suppose that he could have imagined both instances intentionally; in other words, it’s possible that he simply pretended to evoke a frightened emotion for his own personal reasons. But, then again, certain instances in the film do arouse suspicion, such as Gusteau pulling Remy’s ears while Remy was trapped under the colander in Gusteau’s! kitchen. If Gusteau really was a figmentation of Remy’s imagination, then how could he perform physical actions mirroring that of a living person? (And you did point this problem out, I see.) It’s questions such as this that make the film all more entertaining… and mysterious.
Oh and, by the way, you don’t need to place spoiler tags around any information relating to Ratatouille anymore. A healthy percentage of people have already seen the film, so spoiler tags are no longer needed; however, you can still use them if you’d like.

Oh, OK. I did it just to be safe
Wise choice.
What if it was actually Remy’s guarian angel, just taking the form of Gusteau to make him more confortable, and “figment of your imagination” as an excuse to appear in front of him?
B•-R: Yeah, i read part of that fanfic.
What fanfic? 
Oh right, that one. BTW ragdollcorpse, aka Kim, who wrote it, shared it on Pixar Planet.
I wonder what Gusteau meant when he said, “You never did.” when Remy was in the trunk. Never did what? Never had to pretend, never knew who he was, or never imagined? Or all of them?
that has to be a conscience thing…
I was under the impression that it was his conscience/imaginary friend…since Remy obviously was aware of the fact that Gusteau was a figment of his own creation.
