a result of prolonged experiencing of  nonlinear time in the Speed Force.  Several of his comments were clearly him as a child talking to Joe.  One, "I don't think I can be like you, Oliver" was from the pilot episode when he was talking to Ollie bout becoming a superhero.  And "We're going to need more diapers" is probably from when he and Iris eventually learn she is pregnant with twins. [ /spoiler]

Edit:  anyone else think Iris letting herself get captured by the samurai Doombot was a pretty idiotic plan?

My thought:  "Iris has been kidnapped.  Must be Tuesday"

Arrow, which is way darker and angstier, had Sarah going from chained-to-the-wall killing machine to semi-functional in 2-3 episodes

I hated how like 80% of those 4 episodes seemed to be focused on multiple instances of relationship drama. The fight choreography seemed unusually goofy and shitty, like I was watching an episode of Power Rangers except one of the Rangers was punching people with a bow. Iris and Felicity, two tiny women with no powers or any sort of training are now knocking trained Nazi soldiers out with a single blow?

Stein got a pretty good death scene in spite of Jax's acting during it (he's mostly fine, but clearly can't do big emotional scenes like this), but then that's all overshadowed and cheapened by the fact that they don't end on a somber note after the funeral, they HAD to force an extremely saccharine wedding in at the end. It's ok to end on a downer every now and then, ffs. It completely undermined any impact that death and funeral scene had.

Oh and it had to be doubly cheesy by making it a double wedding? AND the only thing Diggle ever did for those entire 4 hours was to come in for the last 5 minutes to wed them? Really? Man, I'm starting to hate this crossover even more as I'm typing this.

- Is it confirmed then that Earth-38 is Smallville's Earth? Seems odd. Pity Tom Welling or Erica Durance didn't make a guest appearance.
- Barry came across as a jackass when he shot Oliver. At least Oliver was trying to make a point... that he himself didn't follow.
- Also, depowered Barry can tackle a speedster? Wtf?
- While the actual superhero pairing we've seen in comics is Supergirl and Batgirl, I wouldn't mind seeing more of Supergirl and Batwoman.
- The Monitor's strategy seems dumb. "Hand super powerful object to random guy and hope he'll provide adequate tests. Guy fails, hand him back the book again." Why not use the book yourself?
