Rigel, as you might have noticed, was in my ‘kids table’ pic as Sirius’ kind of date. Siri denies it, since as a prince, he must eventually mare a princess. Sure, he’s as gay as anyone can be but he has a duty to his subjects. But that doesn’t mean he doesn’t ‘play around’ as Hazy puts it.
While Sirius has dabbled in some relationships, Rigel is the first one he ‘picked up’ on his own. Usually, the dates are blind or Hazy introduces them. Sirius has never stuck with anyone but Something about Rigel compelled him to chase after this mysterious stallion. As such, his mane is going crazy.
Rigel is just happy to see Sirius again. They haven’t seen one another in years and he’s missed him so much. If only he remembered who gave him his name.
Note: Yes, Rigel is disguised Toxic. Toxic never liked changing his looks too much since he took pride in being a Changeling. Still, this time he didn’t want to cause a panic so he disguised himself as a unicorn. He didn’t like pretending to be a Pegasus since his Veil would never have wings.
Also, you might have noticed Rigel’s cutiemark. I couldn’t decide between saying it’s a diseased rotting heart or a putrefied heart. Either way, he earned that heart cause he isn’t the same pony Sirius said hi to all those years ago.
