Ok this will be a little hard to explain and is probably gonna get a shit ton of dislikes because of what is going on in this pic so bare with me ^^;
 
Ok so Ruby has a pretty wired relationship with a the stallions and mares she has been with. Its harder with males as she doesn’t wish to get knocked up by any other stallions than her two main stallion mates who are constantly fighting over her as she can’t settle for just one of these handsome devils.
 
She has know Thorn the longest as he was the changeling she made friends with as a filly and saved from a timber wolf, ever since then they had been close friends until their late teens when the queen had came to thorn one afternoon saying that he and ruby were to be betrothed. This in turn shocked Thorn, not knowing what to do with his and Ruby’s relationship he later talked with her not long into their adulthood, the sane day she had decided to live her own life in the everfree forest.
 
Ruby not knowing what to really say or do just answered him with a kiss and a fairwell message “ my dearest friend should we meet again I’ll definitely consider becoming your queen one day” and with that she walked off into her new life not knowing how complicated it would be.
 
This is where Techno comes in a rugged looking stallion she encountered not long after she become a rainbow factory worker. He is the one who built the pegasus device (hence all the scars and the mechanical wings) who to took a liking to the pretty red maned mare inturn. They started a relationship a few months afterwards and not long after that they become mates.
 
A while after ruby and techno became a pair Thorn finaly finds out where Ruby disappeared to. He heads to Cloudsdale to look for her. He disguises himself in his generic pegasus look and eventually stumbles onto them whilst they are together. Thorn becomes confused due to what Ruby said to him about becoming his queen and convinces himself that Techno has forced her into a relationship with him.
 
He follows Techno shortly after Ruby leaves to head home, he confronts him who in turn is completely perplexed by who he is until Thorn reveals his true form. They end up in a pretty long and tiring fight for the both of them. From then on Thorn is determined to get rid of Techno and take back his queen and Techno is determined to protect his new mate from a mad changling. Ruby meanwhile is happy just having the two if them… but they don’t seem to like the whole shareing idea XD
