Phew, what a relief!
I was thinking that it was the beginnings of the woody stalk at first, but then I started psyching myself into thinking that there was something wrong with my plant after reading about Creeping Nepenthes Death. Sorry, as you can all probably tell, I'm very new to Nepenthes.
As far as the white blob goes, I'm pretty sure that's just the reflection from a droplet of water, seeing as I just misted it prior to the photo. I will give it a closer inspection when I am home though, just to be sure.
