She explained that in developing the relationship between the two: "we wanted it to be real – not some stunt to get people talking. We wanted to see what would happen if a woman suddenly had feelings for another woman." The 2 characters shared a kiss at the end of the season 4 finale, with which D. Williams of "AfterEllen.com" noted: "Callie and Erica became the only regular lesbian/bisexual female characters currently on network television. This is also the first time that 2 regular characters on a network show have begun a lesbian romance, as opposed to one becoming involved with a new lesbian character introduced expressly for that relationship." Before continuing with the storyline, the show's producers consulted with the Gay & Lesbian Alliance Against Defamation to ensure they maintained realism throughout. Trish Doolan, star of "April's Shower" was invited to consult in the workshop sessions which took place, and surmised that; "They were really wanting to be truthful to the 2 characters they're focusing on in the woman-woman relationship", with Nikki Weiss, who also consulted, adding: "they didn't want to stereotype anything either, and write from a place where they didn't understand it. ... I don't think they did it as a stunt to get people back to watching after the strike. I really think that they wanted to develop these two characters, and that you could see a closeness with them way before they ever decided any kind of — I think they just have a chemistry together, as actresses, too. You could tell that in the room. They definitely have a chemistry."
