Yo the finale was lit.
They did Crisis on Infinite Earth’s and Flashpoint Paradox in one.
Plus John Wesley Shipp is the real Jay Garrick which is amazing and Hunter Zolomon looked like he was turning into the Black Flash the way his face degraded and his emblem went red.

Guggenheim: makes sure to emphasize that Katie Cassidy cannot return as the Black Canary. That Laurel Lances death cannot be reversed.
The Flash writers: make Black Siren
The Flash writers: do the flashpoint paradox, essentially providing the TV verse with a hard reset. Leaves us with the possibility that Laurel can come back, and not just as the Black Canary, but ALSO as the Black Canary with a meta human Canary Cry
