Did You Know?


Ralph calls Cicada's ability of flight "Supergirl-ing away", suggesting he's become aware of Team Flash's friendship with Kara Danvers, since in season four's "The Flash: The Elongated Knight Rises (2018)", he doesn't understand a reference to kryptonite. See more »


Iris West-Allen: Cisco, remove the dagger and then breach the atomizer away.
Cisco Ramon: [receiving an electric shock] Yeah, there's a slight problem there. Breaching this thing anywhere could set it off. My powers are useless here.
Sherloque Wells: Then use your other power. Your mind.
Cisco Ramon: Bring up the atomizer blueprints. I'm gonna have to science the crap out of you.

Like lightning through a vortex, so are the days of our lives
10 May 2019 | by crsportsguySee all my reviews

It seems every single episode is a carbon copy of the other. There's always a failed attempt to get the villain, and there's always a parenting conundrum that requires a 15 minute family moment.

This is episode 21/22, Nora has been there the whole season. Last episode she was running with villains, she's been in all sorts of danger all year and we still get her parents saying "it's not safe, we want to protect you?" Honestly, Iris must have taken Barry to the vet to get neutered because he is not a man anymore. I guess that's what made the episodes after the reveal so refreshing. Barry was making decisions on his own without consulting Iris and it actually looked like for once they had internal problems. But she roped him back in and put a stop to that. Every episode I watch makes me wish Savitar had really killed her. Throw in the fact that anything Ralph or Sherloque suggest is laughed at by the team.

Aside from that this episode was okay, from an action standpoint, again a carbon copy......villain escapes, internal debate, big emotional family moment, another villain confrontation, slightly more success, get em next week.
