My Retelling: Twilight is an only child · 10:47am Sep 8th, 2022
Twilight doesn't have a brother. Shining Amror is her cousin. He sometimes drops by. She used to play with him a lot but they grew their seperate ways.
Cadance is very important for Twilight. Cadance is somewhat of a mentor figure. Unlike the reserved sometimes pessimistic Twilight, Cadance is outgoing and optimistic.
(Cadance even unironically ships Sparity saying Spike might grow to be a handsome dragon.)
