Just a little sketch of an idea I had :3
This would take place before Cepheis and Brasheye met and how they met:3

I feel like Aspirant was fine with Brasheye and he might've even gotten along with him at some point
Aspirant might've been the one to introduce Ceph with Brasheye so that he could leave Brasheye in charge of Ceph to keep him from doing something reckless
Everything was fine until Cepheis fell for Brasheye which caused problems with Aspirant when he noticed that Brasheye and Cepheis were getting too close to the point of them becoming matesprits that's around the time aspirant started to grow hatred towards him

Aspirant: *he glared slightly at Cepheis before sighing* you got to be more careful you could really get yourself killed
Cepheis: nonsense dove I'm fine
Aspirant: not when you do something reckless like that you don't have a matesprit to keep you safe all the time and I sure as hell am not around to keep you from doing something dumb like that
Cepheis: you know what would be amazing? If I had my own bodyguard *he said with a smile and laugh*
Aspirant: *he rolled his eyes before stopping* that actually isn't a bad idea I think I might know a troll yeah he's a low blood but he trains a lot so I'm sure he's strong enough to keep you safe
