YMMV / Merlin S 03 E 06 The Changeling

• Big-Lipped Alligator Moment: Grunhilda feeds Elena a live frog. It's never explained, it's utterly pointless, and it's never mentioned again.
• Ensemble Dark Horse: Elena, on account of her general cuteness, being a rare non-evil female character, and a temporary love interest who posed no permanent real threat to any Fan-Preferred Couple. Ironically, actress Georgia King endured some Real Life Die for Our Ship when it became apparent that she was dating Bradley James.
