Dagger doesn't keep his word 90% of the time, usually because it doesn't benefit him. He has major trust issues stemming from his dreadful past, but he hides that with his mischievous behaviour. He likes to see others' annoyance or frustration whenever his pranks get them or slow them down, and he absolutely loves to watch them fall into his harmless traps. No one really likes him, but he has... certain skills. On rare occasions, if Dagger keeps his word or helps someone, it's only because he'll get something out of it. And on an even more rare occasion, he'll do it out of kindness...
