My N. Rebecca Soper smells!

[Zawert]

Ok the title pretty much says it all. My Nepenthes Rebecca Soper smells from one of its pitchers. I found out that it's only one of them, and that it's the one with a rainworm in it. You can only smell it when you get around 3 centimeters close to it, but how come it smells?

- Is it normal for nepenthes to smell when they digest their food?
Cause if it is, I won't be able to have it in my room I think..

Thanks in advantage :-)
Best regards,
