No, but it's not there on accident. I never for one moment intended to kill Aura. Not dead, never was dead, that's why Polaris says nearly.
As for jobbing, I'd say that's a bit of a stretch, as well. Polaris is the premiere magnetism master in the dcu, Aura isn't even in his league. And Repulse was his dark side completely unleashed. AND she was taken by surprise in a planned ambush.
That's not really 'jobbing.' If Darkseid defeats Captain Cold, it's not really jobbing. It's the only logical outcome.
