Don’t think Ruthye will get the Supergirl title frankly. Another white passing alien becoming the new Supergirl? Unlikely in the current era.
They’ve teased it a couple times but it’s unlikely. Jon is the focus and a daughter at this stage doesn’t really fit in their plans. I’m sure Taylor is pitching to bring his Injustice OC daughter into canon though.
Which is also her characterization post-FP as well. Wholesome Pre-Crisis Kara hasn’t existed since CoIE frankly.
TOTALLY disagree. You refer to an adult female as a “girl” instead of a woman and you’re going to get a reaction and it probably won’t be a positive one. This simply a signifier that Kara is an “adult” and is moving into a new stage of her life like Jon and Clark are.
