Personally, i think she was affected when they used the particle accelerator on Barry. There is no way they could use it twice and she not get powers. Personally, it would be stupid if a supervillian change was triggered by a romantic break-up. Besides, Barry is already with Iris. What would be much more interesting is if her PTSD situation caused by Zoom did it. Then the cold feelings on the outside and inside trigger her powers. Barry would feel guilty that he didn't stop Zoom fast enough and he let this happen to his friend. Since Ronnie is dead, she will need a heat source due to sucking on people's heat, she would steal it from Barry because although his suit is heat resistant. He still collects a lot when he runs. This would make a good season long villian, a main threat that knows everything about Barry and the group.
