btw, since when does Nick have an enhanced sense of smell? The book isn't canon, right? So I guess the author just added it to Nicks special Grimm-Talents, but it makes sense in a way. Enhanced hearing, enhanced physical abilities, enhanced mental abilities, so why not enhanced sense of smell...

It would follow that it was heightened when he was temporarily blinded, just as his other senses were (with the exception of sight). However, Blutbaden are still the better scent-trackers.
