Almost everypony has a soul mate, one they are destined to live with and love for all their days. They give their body, heart, and soul to each other. Rarely do soul mates ever change, but occasionally there is the twist of fate that happens.
During their escape from the crystal caverns, a lose rock manages to almost impale Twilight before Cadence pushes her out of the way and takes the blow. Seeing her foal sitter dying, Twilight uses all her magic to save Princess Cadence with a very dangerous spell. It is not without a consequence as she, unknowingly, gives her own life energy to Cadence, tearing up the soul bond between her brother and her foal sitter. Instead, it makes a new one: one between the two of them.
With Shining Armor’s own bond broken, it attaches itself to the closest being it can: Queen Chrysalis.
