Trickthorn's Links
He has a great fear of Douseflame, the only one who has ever seen through his lies. If they'd met sooner in life, perhaps Trickthorn would never have hurt anyone.
He hasn't forgotten about Trickthorn even after so long. He won't go out of his way to hunt him down but has no compunctions against killing him again.
He chose to torture Errantpaw because his outspoken nature differed so much from his own. He was always aware that Errantpaw wasn't capable of killing him.
He's still incredibly frightened of Trickthorn, becoming nauseous at the mere mention of him. Even after moons of pain at his claws, Errantstep still doesn't understand him in the slightest.
When he was deputy, he always worked hard to follow Quickstar's orders. He fostered some hidden resentment toward him, but mostly felt arrogant that Quickstar never noticed anything awry.
He's disgusted by Trickthorn's actions and wasn't able to accept it. He took out the pain of betrayal on Douseflame.
