It was temporary, thankfully. I flatlined after an attack at S.T.A.R. Labs. The team took my necklace off so my powers would keep me alive. I thought I wanted to be evil for a few months, but ultimately, I couldn't do anything to hurt anyone, not really, and I realized I could have my powers and be good, too, with some work.
How's the Waverider? Or, well, how was it before you left?
