'Grimm' Episode 7 Photos: 'Let Down Your Hair'

Attention fairy-tale fans: It's "Rapunzel" time on Grimm! Of course, because this is Grimm and that other fairy-tale show, we can expect this Rapunzel story to be significantly twisted and dark. Also, there's a chance that Rapunzel is a monster. "Let Down Your Hair" will air on Friday, December 16 at 10pm (note the special time!) on NBC.
