Yeah, I get it.
In my head canon, that was Deborah Domaine and she was just 'filling' on Barbara while the latter was chilling somewhere else.
Rucka's pairings can sometimes feel like fanfic OC being paired with canon characters or just full blown escapism. The former definitely applies to Sasha Bourdeoux's romance with Bruce. Meanwhile, Cheetah, 'the sexy cat lady' gets paired with Snapper Carr who is basically an in universe fanboy and earlier with Hunter Zolomon which qualify for the latter.
Aside from Cheetah in his first run (which he made up for in his second) and the WonderBat ship teasing, I otherwise think his ideas for Diana's universe are on point.
The WonderBat shipping is weird because he's the only writer who goes for that who writes her character well. But his Bruce is pretty meh. He's like the anti-Bruce Timm.
Yeah. I like Sasha, but she may be the most prominent fanfic-ish OC pairing for Bruce we've seen. Silver would be the next one down.
And I like Silver too, but it is kind of amusing when a writer is transparently shilling who they believe is Batman's One True Love, and then that character vanishes when they leave the book and Selina comes back.
I think he only really shipped them in post-Crisis during the BN mini and because options like Trevor were off the table (because Steve has all the benefits people ascribed to "WonderBat" but with the key added benefit of not being Batman ).
He also wasn't really interested in romance in his first run.
Superman and Batman shouldn't be best friends

~I just keep swimming through these threads~
They can be working friends or friends but best friends? No, not the way they’ve been written for the last 20 to 30 years. It just feels forced. They are DCs two most popular characters so let’s just make them best friends.
For Clark you’ve got Peter Ross or Jimmy Olsen, John Henry or literally a number of other heroes

Barbara Minerva was very much a See It, Want It, Take It type of person. So it never bothered me to see her be so forward with Carr or the weird talking yellow flash guy. This character trait was how she got her powers originally
