LMAI've enjoyed getting to know this Lois, and I can see her differences really playing up well with Alt. Clark. They are both different from the originals, and I love that you are taking their reality, their personalities, and their histories and making them their own.
Since we were never introduced to Alt-Lois in the series, she is pretty much a blank slate to work with. In some stories she's really sweet and approachable and in others she's a little scary. This is my take. Hope you like the way Alt-Clark is portrayed!
