I think when he first shows up on The Flash they make a Supes joke.

So I just realized and will probably make this comment after the next Arrow that while this one was the most internally focused of the three, it's also the one that had the least do with the current plot lines. On The Flash when Barry came and got them it had more to do with what is currently happening on Arrow than…

On the closed captions Aberration is capitalized.

Did Kara even have a chance to find out about Alex and Maggie?

At least the show admitted that Nate looks like an idiot.

Yeah, but they explicitly spelled out how Citizen Steel came to be.

Haha

Nor why future Barry sent it decades later.

Cisco's 5 minutes in Earth Thirty-Eight don't count?
Who I am kidding of course they don't.

Agreed, in the Venn diagram of viewership of the three shows, that one has got to be the smallest subsection.

"I have no idea who this is."

I didn't think about how long it took to make, and you're right. My thought was on how small it was, some dialogue about how it has to use her Kryptonian biology and/or only works between these two Earths would've been nice.

While I still really enjoyed this, I have to agree it was the weak link of Invasion!.

I also rewatched the scene with CC on and it looked like all of the captions just said [speaking gibberish].

We don't even know if Earth 1 has a Krypton.

Yes, it wasn't me though, cause I didn't even catch it on second viewing. It'll give me something to watch for when I rewatch the whole of Invasion! tonight.

I think I remember that but that is about where I watched off and on.

As for your 1st sentence that occurred to me when I was thinking about how Supergirl (ie the show) had almost nothing to do with the crossover and then during the actual crossover it really didn't get bogged down with lore from her show. There's probably a decent amount that only watch her show and vice versa that…

Though back on Arrow before Legends started they established that Ray is a Whovian. Unless I've missed something (which is entirely possible I've never gotten into Who and only watch a few episodes every few years) they've never played with that on Legends. Maybe they're saving it for the inevitably return of Rip…

With the reveal that the Dominators came the first time because of the JSA it reminded me that there has been previously been one meta from Earth 1 that wasn't in Central during the particle accelerator explosion or changed by Alchemy. They've never followed up on that.
