I reallllly wish there was a bigger fight sequence.
I do think what happened to her had to do with Saturnyne and the Starlight Sword though. Jamie did probably have a hand in.... something. But as soon as she uses the sword, that happened. And Saturnyne told Brian that if he'd only picked the right sword. So she knows what's going on with Betsy obviously. Can only hope it means a triumphant return to the fray when the real fighting starts.
