Erica is THE greatest Lois Lane of all time. She played her for so long and at such depth that no one else can touch the way she realized and identified the heart of the character. I know she was ultimately unsatisfied with the way Alex was developed on 'Saving Hope' (she repeatedly asked that Alex be lightened up a bit and that she not be in a constant loop of never learning from past mistakes) but she made her mark there as well. I hope her run on 'Supergirl' brings her professional fulfillment while its part-time nature also allows her more time to be with her children.
