S4:Ep.4: This scene lasts for 16 seconds. Lex is yelling at her from somewhere to come and change his bandages. Apart from the fact that the pentacle has fallen off her hand, what's with the dark chin paint? Actually in close-up it looks more like doodles with a blue dry marker or similar. Apart from stopping to stare after eye-candy Pride, she makes straight for Lex.
And when she gets there - her chin makeup has all gone.
Next we see her being stroppy with Lex and Salene - a quintessential stroppy teenager !!!

Pentacle on her left hand as normal (for Cloe), no chin paint.
Cloe attends a ceremony conducted by Salene to remember everyone from the tribe that's missing. Cloe's chin paint is back.
