Blitz and Fog both had hired their friend Opal to help with their training as, Blitz wished to be fit enough to win her boxing matches and Fog was hoping to become a new wonderbolt like her mum, so when the unicorn found out the two were brother and sister she couldn’t help but to do a joint training session. Opal had invited the siblings to a practice session as Fog arrived, he noticed his sister there and instantly froze, glaring. Opal was making Blitz do wing ups before they both turned to see the newcomer, Opal gave a small smile with her tired looking eyes, Blitz was glaring back at the colt as they both walked to each other. Opal curiously walked to them both. Both Pegasus’s feathers went up as Fog looked at his sister, seeing a medal making him scrunch his nose in annoyance.
 
“The hell you doing with a medal at practice?” his voice sounding irritated and snarky. Opal gave an anxious look and stood looking at the two as Blitz gave a bold look.
 
“I was showing it to my friend, since she asked. It’s none of you business anyways” she lifted her head to her height advantage as Fog gave a look at Opal.
 
“I thought I got private sessions, not sharing it with this show off” The colt looked back at his sister as Opal felt herself regret the decision about to answer before Blitz talked.
 
“Don’t blame her, Frog” she spat his nickname out before Frog glared at her.
 
They both continued to fight and argue with each other as opal waved them off with a tired look
 
“If I knew you two were like this, I wouldn’t have bothered…”
 

 

 
Finally some actual story, well not that good asleast. But from this I made it that Opal was both their personal trainers and such. Blitz is definitely the more accomplished sibling which annoyed Fog alot ending up in arguments whenever they meet each other.
