'Grimm' Clip: Adalind's Terrifying Paternity Test

Grimm fans have no great love for former Hexenbiest Adalind Schade, but even the most cold-hearted will feel for the mom-to-be when they see the disturbing examination she's about to undergo on Friday night's episode.

In the Grimm installment (originally scheduled to air last week but pre-empted by news coverage of the search for the alleged Boston bomber) Adalind (Claire Coffee) visits the encampment of a new ally (Shohreh Aghdashloo), where she's asked to prove the royal bloodline of her babe. Despite Adalind's insistence on the paternity of the child-to-be, her new "friend" needs proof -- which comes in the form of a giant metal needle. Watch the clip to see Adalind's terrified reaction!
