Speaking of bloopers, Eliza told us a story yesterday about freaking out when a wasp flew by her in season four during her speech at the end of 4x02. Apparently she is very allergic, so she freaked out in the middle of this super dramatic speech.
And during 4x05, when she is standing there as Ice Nation approaches, a bear came up in the distance behind her, so the crew said, "Eliza. We need you to walk very slowly and quietly towards us and DONT LOOK BEHIND YOU."
