Charlie loves musicals and rainbows. She whirls through a hundred ideas a minute, trails after sudden fixations that catch her eye, seeks out what will wow her. The loud bits that stand out when you fast forward through a song.
Life...
(is it technically life when you're an immortal Hellborn princess? Well, anyway.)
Existence, then, is on fast-forward for Charlie. A constant compulsion to do & experience as much as possible. Yet at the same time, things pass her by – she sits down to focus on one particular task and then suddenly it's hours later. It frustrates her.
Big things get Charlie's attention; the loud bits that stand out when you fast forward through a song, the bits that make you stop, rewind, and listen properly. Fast, loud music. Visual spectaculars; fireworks, bright colours and dancing.
Vaggie, in a quiet way, stands out in how she tells Charlie why rather than just no. How she gently tempers and also enables her ambitions and dreams. It's a contrast to the judgement she's used to getting.
Vaggie is Charlie's anchor. A pause button, a respite before she's ready to fast forward again.
Headcanoning here that Charlie has ADHD. I am diagnosed with ADHD, and I can relate to a few of her character traits from the pilot - e.g. seeking or being drawn to big, bold, exciting activities, displays & experiences that get the seratonin going; making spur-of-the-moment choices & decisions.
