Kara is put into a vulnerable position when she instinctively steps in to help during an attack. She is at risk to be outed as Supergirl. She has bigger problems, though, when during the attack, Kara is exposed to Kryptonite and an unknown substance. What is that substance? Who will be let in on Kara's secret? And who is behind all of it?
