Nogrod good enough for me.

When I asked it was kind of a spur of the moment thought, like...wait why would he assume
Nerwen was the "free kill?" Not thinking about the lynch yesterday where we now know
Shasta could not have dreamt of
Pitch.
Also, taking into account what Inzil has found today (readily available indeed!) it appears our Ranger was telling us he guarded
Nerwen the previous night. Which the wolves would probably have been looking for and thus were able to target
Glirdan.
Edit: crossed with Nog
