Burning Love: Spiracle & Burning Love first met in Ponyville, back when Queen Chrysalis ruled the hive, planning to eventually attack. Burning had been living there for quite some time, while Spiracle, disguised as a unicorn named Spiral Hoof, had been sent there as a scout or spy, for long-term reconnaissance. Burning Love offered Spiral Hoof a place to stay. They eventually grew closer as time went on, developing a mutual crush. Spiracle was fond of Burning Love's capacity for unconditional compassion, while Burning Love adored Spiracle's patience & for being such a great listener.

However, it was only until the ascension of King Thorax, that Spiracle began to fully realise & acknowledge the love she felt; but she had no idea how she could properly reveal herself as a Changeling, now; much less how to confess her love. Then, in a late-night conversation about cutie marks, Burning Love brought up her past experiences of feeling like she had to hide her magic, & subsequently hide her true self, before letting it out in the open. That conversation then gave Spiracle the courage to admit the truth the following day, during one of the festivities celebrating the Changelings & Ponies' newfound alliance.

After that, the two began officially dating, eventually getting married & moving to Heartshare Valley.
