I see your point about families. But when it comes to Dinah and Babs and Ollie, I would think that Dinah would be likely to intervene before things got too bad. I mean, she's not going to take kindly to either Ollie or Babs completely ragging on the other. If she didn't intervene, Babs and Ollie would be looking at a situation where Dinah would be hurt by and pissed off at both of them.
If she leaves the mix, then what do you have? Ollie and Babs sitting around yelling at each other, with no Dinah, who was the one they both cared about in the first place (and that's where an evil writer would try to make Babs/Ollie happen just to fuck things up entirely). So to avoid that situation, I can see both reigning it in and trying for the grudging compromise thing.
(You've also got me thinking about the occasional fractures in my own extended family, and I think the method there has mostly been avoidance. =/ )
I like to think that too, but the evidence is somewhat against us. ^_^
*sigh* You know I'd like to see? A story where Kory and Babs have to work together on something, and you, you know, have the expected tensions at first.
BUT THEN, they get a chance to see exactly what kind of superhero the other is, and they come to really respect each other as a result. And there would be absolutely no mentioning of Dick or him appearing at any time.
And if you wanted them to actually like each other, maybe something could happen like the Commissioner almost getting killed, but then of course Kory saves him. So you'd have Babs all "OMFG thank you!" and Kory would realize "hey! she's not a heartless bitchy robot!" or whatever. Then they could be sorta friends.
Because, as we've discussed before, I hate how Dick/Kory so often comes off as a dis to Babs, but if Babs and Kory actually got a long, that potential wouldn't be so bad. Even though I still wouldn't want Dick/Kory to happen. *I'm* petty, but Babs doesn't always have to be! lol
