Is it a rule that fan theories have to be so dark?

You ever watch Gabby's Dollhouse?

She stays in her room, full-time. She never interacts with anyone outside of her room. She receives deliveries from an unseen outside force, via a cart and ramp system that makes interaction between inside and outside impossible. She then uses her anomalous abilities to shrink down inside of her dollhouse and have adventures in a pocket universe.

She's happily protected, in a contained, secure area which she never leaves.

Gabby is a comparatively benign SCP.
