They are unnecessary because 99% of the characters are identical. They have the same exact history. I know it isn't confirmed, but come on you all know it's true. The CW treats it like that and doesn't bother to reintroduce characters or anything. Like I said before, This is basically just splitting the character's history on december 10th and deciding to just cover what happened to him after and before on 2 seprate articles.

I mean imagine when Alice shows up. She and Kate will talk like "remember that car accident". Then the wiki will be like "It seams Alice and Kate got into a car accident. The exact details of this incident are unknown". And the thing is: we know about that car accident. The details are known. We know that it's the one where their mom died and Batman failed. That's just weird to pretend like we suddenly don't know what happened. But we apperenatelly have to, because it's not the same earth and it's not the same Alice...

Personally, the only argument I've heard that it is necesarry is because "they are different for example Diggle now have 2 kids we need to say that". Well yeah, but it can be done like a timeline change... There are probably more arguments I don't know about and I'm open to hear
