On Supergirl almost everything can be explained by "bad writing." Simultaneously nice to know and depressing that it also applies to the other shows, including Black Lightning.

I also wanted to see Cain and Hatcher from Earth-93 but alas, such was not to be.

If the endgame is to put everyone in the same universe like in the original Crisis we could see lots more Black Lightning going forward.

A few random thoughts from a Supergirl fan:

Lex not knowing his Superman is Clark even though somehow he knows Kara is Supergirl was jarring. To me, it doesn't make sense.

I really chafe at the idea of an antimatter wave moving through space and yet destroying worlds that aren't in the same dimension. It wouldn't have taken much to say the wave was spreading from one universe to the next.

A few random thoughts from a Supergirl fan#

Logistically, there wouldn't be 3.5 billion, more like a few thousand. Plus, when it's over Kara and Clark will have to find jobs, establish new secret identities, etc. And Lena will be broke with no resources. I wonder how they're going to hand wave all that away?

My usual random thoughts, from someone who only watches Supergirl and Black Lightning:

Which could easily take place on another Earth as part of the Crisis or be subject to a reset, again as part of the Crisis. IMHO, the “tell” is that she’s wearing the super suit under her regular clothes. Why would she since that’s no longer necessary? The jury's still out.

But it wouldn’t necessarily work out that way. There’s an old silver age story from Superman 197 where Clark is presumed killed in a glass factory explosion (really) and Superman decides having a secret identity is a PITA. He tells Jimmy Olsen he and Clark were secretly roommates (again, really) and suggests a similar…

Leviathan has been around for about 65 million years. Rama Khan had been their leader for 2 million. They were responsible for the extinction of the dinosaurs when their ship crashed. And remember, they came to Earth in a starship that long ago. Seems like they should be more advanced.

Saved Kara’s bacon or not, Andrea would still be an asshole. Bad people can do good things and still be bad. I wonder how far Kara's "look for the good inside" attitude would go?

Part of me says Dreamer wouldn’t have been any help but another part remembers her stopping a tidal wave with “dream energy” and thinks how handy she would’ve been dealing with the volcano.

In past “imaginary” (non-canon) comics she’s changed her name to “Superwoman” when Superman retired or disappeared. The current name is an unfortunate holdover from when “Supergirl” originally appeared in her early teens and we’re all stuck with it.

There’s only one supervolcano in North America in our version of Earth. Their geology could be very different. There’s also no National City and Metropolis is a small town in Illinois. That alone should be sufficient proof.

Disagree somewhat about Lena. It's not necessarily that she's "a Luthor at heart" but she has a warped way of looking at things. Whether she can be redeemed remains to be seen.

My usual random thoughts:

I noticed. But strictly speaking someone who is 65+ million years is thousands of years old—about 65,000 thousands but still thousands. These people also believe Noah's flood was a real event and probably that he got all those animals in the ark.

Do they know Malefic had help getting out of the Phantom Zone? If so, they might not expect him to escape again.
