This anomaly will look pretty familiar to anyone who watches The Flash, and this is obviously a prelude to the big CW crossover event based on DC's Invasion!, but before we find out any of that, we have this episode’s weak-sauce A plot to get out of the way.
This week, the DC/CW superhero shows launch their very first four-night crossover event, and most of the episodes are all titled “Invasion!”, and if you’re a comics fan you probably already know this crossover is loosely based on Invasion!, DC Comics’ company-wide event of 1988.
The Flash crosses over from the CW to hang with Supergirl, and this superhero team-up is basically everything that Batman v Superman was not. For starters, there's ice cream for everybody.
When Booth and Bones come to Sleepy Hollow, even an army of zombies somehow can't keep this crossover interesting.
Season finale time! Team Arrow fights to save Starling City from complete destruction, and before it's all over, there's a new Ra's al Ghul in charge of the League of Assassins. Plus, Oliver ends up happy... but how long can that last?
