Rescue bots; Heatwave's secrets

Heatwave has been a questionable bot for quite some time now. He prefers hiding his emotions and whenever someone says something about his birth family, he always avoids the topic. This was unusual to everyone, but it become normal after a while.
But, there's always a person that gets a story going.
Cody Burns. He was always suspicious of what the red and yellow fire bot was hiding. He knew something was wrong. And with that, curiosity got the better of him. Cody was going to figure out what was wrong with Heatwave.
But most importantly, why.
