We're actually team green and I wasn't really looking for any nubs but when I got to looking at my 12w scans again I'm wondering if that little line is a nub? Thought I'd post and get some thoughts on it. :)
I'm also not sure what to think as far as the skull theory on this one either. It's fun to guess!
