The urge to shout, to fight Adora for more information is unsettlingly strong, but a deep breath lends Glimmer some patience as she watches Adora expose her arm - she's frowning intently, but as soon as those purple marks are exposed she gasps sharply, both hands coming up to cover her mouth.

Her aunt Castaspella is a massive gossip. Glimmer's heard stories from her about what dark magic can do to a person, and that is... disturbingly similar to how she's always imagined it.

It takes a conscious effort of will not to step away from Adora, and to instead take a step towards her, but she manages it just fine. She knows if she backs away Adora would never show her again - for better or worse. She reaches one hand towards Adora automatically, but clutches it back to her chest when she realises. "Does... does it hurt you? Are you alright?"
