“Look Bella, isn’t is beautiful? I wish everypony had just a second to look up and enjoy the glithers of thousands of stars, the lights, the colors…”  
“Yeah, it totally makes worth it the three hours we spent walking and that it’s already 3 am…”
 

 
In case you don’t remember (or maybe I haven’t made it clear), Ceres’ special talent is stargazing and he really enjoys to share what makes him happy with his friends.
 
Bella and him met thanks to Ceres’ grandparents. Bella takes care of Night Light and gives him and Twilight Velvet some company. Since Ceres spends pretty much time in Canterlot with them, they ended up growing such a strong friendship. Bella of course finds Ceres absolutely adorable, like a tiny kitten.
 
You know when you try so hard to make a non-straight ship with a new character and then you remember you have a child that deserves all the love and you instantly ship them? Why do I find Ceres so cute?
