What am I now? Well, that's simple question that requires a overly-complex answer.
Let's start at the begining. Regulus' mind is made up of aaaall sorts o' fragments. I represent joy while the Regulus you knew represents hate. There are many more fragments in there, but they havn't awakened yet. Lazy bums.
However! Each fragment also has one or more sub-fragments. In my case that would be... Well, no idea really.
Anyway, when Anger got rid of me, it forgot to take into account that I have several sub-fragments, and thus it actually got rid of just a part of me.
With me so far?
