has come to an end.

OK, confession time: this episode had very little to do with the actual crossover.

In fact, it was really just the Supergirl midseason finale.

Thats fine, though.

Given these shows notable departure from that stuff, though, its probably just a coincidence.

The Flash Season 3 Episode 8: Invasion!

Holy moley…they actually put the Hall of Justice on TV!

I imagine well be seeing this again.

They had to dig deep for that Julie Greer byline.

That Julie Greer was a TV reporter.

This isnt a character of significance, though, so dont worry about that.

Because this is kinda cool.

What the hell isGenerations?

So why is this cool for Supergirl?

I wouldnt ready anything beyond that into it, though.

Or, more succinctly, Superman first appeared in 1938, so draw your own conclusions from that.

And for real, wouldnt you?

If you believe that sort of thing.

Which I usually do, I might add.

Weather balloon, my clavicle.

Arrow Season 5 Episode 8: Invasion!

Oliver (Stephen Amell) wakes up to a life where he never got on The Queens Gambit.

Laurel (guest star Katie Cassidy) is his loving fiancee and their wedding is imminent.

Everything seems perfect, but Oliver starts to notice small imperfections that make him question this new reality.

Black Canary has been given that necklace before.

Van Horn Industries is a reference toBloodline.

A race of parasitic aliens invaded Earth killing most of the humans they came in contact with.

One of them was Andrew Van Horn, the son of a Parisian industrialist.

In case you cant tell, these comics wereawful.

Legends of Tomorrow Season 2 Episode 7: Invasion!

Brandon Routh, Franz Drameh, Dominic Purcell, Maisie Richardson-Sellers, Nick Zano and Caity Lotz also star.

She is quoting Darmok, the second episode ofStar Trek: The Next Generations fifth season.

So I think we need to talk about this G-Man played by Doc Cottle fromBattlestar Galactica.

Faraday was created by Bob Kanigher and Carmine Infantino in 1950.

No I have not so I will thank both you andKing TChallato stop referencing it.

She kinda looks like my cousin.

I love Brandon Rouths superhero second act.

Kara to Ollie and Barry before she leaves: Youre Earths mightiest heroes.

KARA SHH!DYOU WANT TO GET SUED?

Smart money is on her only needing it one more time, though.

If I were a gambling man, Id bet that next years crossover is some sort of…Crisis.

And while we have you, check out our own behind-the-scenes video from the crossover, too!
