Jenny's accessories investigation
In episode 104 Jenny is intentionally flirting for the first time with Emma, drinking champagne with her after their first successful work-day at Saal1 and is furious about Emma's prejudices against lesbians. Afterwards she is deceitfully turning off the alarm system to get rid of Emma. She is wearing the vampire necklace here. A hint to sexual tension, erotic, but also firy anger and shadow sides like deceit? ... thoughts?
In episode 105 the plain truth comes out. We see how furiously Jenny is defending Emma - and how she herself is surprised by her own reaction and wants to hide it. In this scene Jenny isn't wearing any accessoires (of course it's also because she's about to play volleyball, but...) - unveiled Jenny showing bare feelings?
In episode 114 Jenny starts to take responsibilty for her actions and feelings in relationships. She apologizes to Hotte and makes clear what she really feels (or not feels) for him. And later she makes clear to Emma what she really feels for her. She needs courage and willpower for it and also some fortitude to confront Hotte's and especially Emma's reaction to her. So a lot of sunpower is needed (big sun necklace) and the ruby broach on her left (heart) side might also show that she dares to stand up for her true feelings and follow her heart (whether it is to Hotte or Emma)
In episode 145 Jenny and Emma fight over the meaning of Jenny's one night stand. Jenny's upset that Emma doesn't want to understand that it's totally meaningless for her. She's hurt that Emma is doubting her trustworthyness and her love. When she's rushing off to get some distance between them Jenny puts her sunglasses on. Some protection and also a barrier? No one can see through her eyes into her soul. In addition she wears the red lava drops necklace at that moment and later when she sees Emma kissing Luzi in order to hurt her. Jenny's kind of a volcano - like Libelulle fittingly stated.
