Honestly the depiction of Gwen as a family-oriented or maternal figure would be a major change to the character. They have continually sent signals up that show her reticence towards settling down, getting married, and even her threatening to Rhys that she'll abort her baby in CoE have indicated that it's likely just not in her to do those things. Of course some people don't express a desire for domestic life and then adapt very well, but it would seem in character to show Gwen trying to escape from the domestic "mess" that she'd created for herself, probably with some idiotic analogy comparing her to a wild horse running free across the American plains.
