We heard recently from executive producer Andrew Kreisberg that there will be bumps in the road for Alex Danvers and Maggie Sawyer when Supergirl returns starting January 23rd. But now, he's back to let us (through EW.com) know that the show is really investing in the Alex / Maggie dynamic.
The important thing is that we're committed to this relationship and we're committed to seeing it grow, change, blossom, and struggle, but also get stronger, deeper and more loving as we go forward. I don't think people need to worry that suddenly this relationship is going to go by the wayside. It's going to have it's ups and downs, but we're committed to Alex and Maggie — we're as committed to Alex and Maggie as the audience is.
Now the big question comic fans want to know is if there will be any hints at Maggie's previous relationship while work in Gotham. Will there be any Kate Kane / Batwoman Easter Eggs?
