The studio must have the air conditioning on at full blast during taping. I've noticed the mannerisms for a couple of weeks. But, it really became obvious today. Olivia is shaking like a leaf in all of her scenes & rubbing her bare arms frequently. It didn't distract me because she was very emotional, but.. Then, both Claudia & Carly (Claudia especially) were both burrowing under their blankets. Kristina was also doing the Brenda Barrett (pulling her hands inside her sleeves). I've seen other instances, too. It would also explain why so many characters are wearing jackets & sweaters in June & July.
