Once upon a time, when Copcar was a little bit younger than today, they were rescued by a handsome red courser. Tall, beefy, strong, with red hair and the very bluest of eyes. They were gorgeous, and Copcar swore he'd never let it happen again. That handsome rescuer would never know that Copcar briefly though that they were cool, and handsome, and just so incredibly capable. Truly, how could ANYONE be so good at everything (author's note : Firetruck is not good at everything. There's several areas in which they struggle. Copcar is a poor judge of character, especially when they're feeling vulnerable, and they usually are a little vulnerable. A little too damp to callous).

However - Firetruck hadn't noticed when, after taking Copcar back to his home - their home, if Copcar wanted it - to make sure the lost-and-found paint wasn't secretly wounded, Copcar had snuck from the house with more than a few long red hairs clutched to them. Took it to his actual home and given it to Wee-woo to braid - she was surprisingly dexterous, though it probably shouldn't have been surprising, as her toes could go in all manner of direction - and then attached it so it hid underneath their mane. To, uh, remind the paint that they had a life vow connected to the chestnut - a vow of hate! And feeling! And vengeance!

It wasn't that Copcar was trying to make sure that they would never forget Firetruck... or maybe it was, to seek revenge! But that was it.

They had made a life oath, and would never rest (without a piece of Firetruck close).
