There's a lot she could say to that - no of course not everyone knows everything, but there are so few of these creatures, wouldn't they try to share their knowledge about something as crucial as this Door? As for honestly, well. She certainly doesn't trust anyone, always has to watch her back. That's normal. She doesn't expect honesty, just knows most other creatures in the multiverse do.

But, fine, Rage seems ready to move on and Caedra suspects pressing the issue wouldn't get her any farther.

"Fine. No, I don't. But you've done a fair job of convincing me that you are utterly useless, so congratulations there. I had come to you suspecting you might at least understand where I'm coming from. If you thrive on pure rage, then there are probably none here who can serve you better than myself and my people, but perhaps I'll have to go elsewhere. I can generate quite a lot of sorrow or fear as well. They can take credit for saving your race rather than you."

Either she'll get curious, or Caedra has begun to burn what might have been a bridge, but if Rage continues to act the way she is then she doesn't deserve the deal she can offer her. They go through so much effort to run from the Null when planehopping is child's play to her and her companions in the Abyss, after all.
