“In our world strong-willed women and women who are powerful in their own ways tend to have other things going on, so we find out that there are secrets,” Jordan told EW. “But for the first few episodes that we see Winn and Lyra, it’s more about discovering how their relationship fits into this new world that we’re discovering on Supergirl.”
And part of that discovery will involve Lyra joining Team Guardian on their missions and possibly causing a falling out between Winn and James (Mehcad Brooks). Executive producer Andrew Kreisberg also shared with EW, teasing there will be a big hour for Winn, James (Mehcad Brooks), and Lyra (Tamzin Merchant) in episode 16, as well as episode 18. “Winn, James, and Lyra have a really funny story in 18 too, where the three of them try crime fighting as a trio, which doesn’t necessarily go well. She kind of becomes the Yoko of the team.”
