Did You Know?


After Grodd is defeated he is mentioned to have been detained at A.R.G.U.S, Caitlin states that he can be thrown into the same cage as King Shark for all she cares, since any good in him is long gone. Cisco then states that was a fight he'd pay money to see, subtly foreshadowing the season 5 episode, King Shark vs. Gorilla Grodd (2019). See more »

Gypsy: All right, well, if the city doesn't need my help anymore, I'm gonna head back to Earth-19.
Cisco Ramon: Oh, really? So you did all this for the city, huh? 'Cause I'm pretty sure there's a different reason you chose to help us.
Gypsy: That's right; I was the only one who knew where Solovar was.
Cisco Ramon: Oh, right, yeah. How could I forget?
Gypsy: Mm.
Cisco Ramon: Don't front. You're into me.
Gypsy: Look, Cisco, I mean, even if I was...
[kisses Cisco]
Gypsy: You couldn't handle me.
[she leaves]

Bring back Savitar!
16 August 2017 | by asb_deutschSee all my reviews

These episodes remind me of Season's 2 - "Welcome to Earth 2" and "Escape from Earth 2" It was the needed exposition for the new world in which we're introduced in which is Earth II. I rated both episodes 10/10. Episode 12 was a spent forced addition and couldn't match Grodd what ZOOM was so threatening, though he looked cool in the armor.

Although we didn't get a ton of time spent with the three speedsters, Jesse, Barry, and Wally, everything was balanced out incredibly well. There was just enough action, intrigue, and tease for the future to satisfy my needs for the show.

Iris and Wells giving pep talk to Barry Allen was nice, explaining how Oliver Stone bears the weight for the killings he done.

The main issue was the fight between Solovar and Grood was more funny than absorbing. I mean they looked like big soft hush puppies. May I am comparing with the SFX of Planet of the Apes!
