I haven't liked Fiona from the beginning and last night I really disliked her. She was quite spiteful and I hope she's out tonight. She has enjoyed swanning around feeling in charge, and was furious that Amanda had confided in Rachel and not her. We saw another side to her for sure.
I still don't understand why Reece ... or somebody ... didn't tackle her over her not bothering to collect any skulls on the mission. She made a strange comment while she was in the woods pootling about, saying she had all the time in the world, while poor Reece was waiting in the cage calling out for her. She deliberately sabotaged his chances of being released.
The names of a psychotherapist and counsellor come up in the credits, so Reece will have someone to turn to. People have suggested that Reece could be Fiona's son. If he were my son, there's no way I could have sat opposite him at the round table while he was upset and not got up to comfort him.
