Well good to see Mia Queen again. I wonder if they will continue her storyline in Flash now that her spin-off show fell through.
It should've been revealed that Despero actually caused Armageddon by trying to destroy Reverse Flash. Then Barry could reason with him by applying Captain Kirk-like logic and telling Despero that since he caused the end of the world and his mission was to destroy whoever caused it, he must therefore destroy himself.
I wish we had Matt Letscher as Eobard Thawne instead of Tom Cavanagh. What's the reason for still wearing Wells's face now?
Why is there also such a long break until Flash returns again next year? It seems to be coming back in March, which is a bit overkill for a Christmas break.
