I didn't think of that one! Maybe Merlin had to be concentrating on her to block her powers! That would explain all the strange looks. Though he did feel the energy being sucked away through the knight when he was away from the castle, did he not? I really want to know why Morgana went to the room (presumably hers?). Just to hide in there, hoping Southrons will find her and escort her out, or if she really did suspect a poppet (she's a High Priestess so she should know about them, and she also put the root under Uther's bed so she knows that these things can be put under beds), take it out, then decide not to fight Gwen with magic.. perhaps in case it didn't work again, or she wanted to finish her off with a blade alone to prove herself.
