Quotes 

• Killer Frost : [to Cicada]  Let's dance, cricket face.

• Nora West-Allen : What if we could make one?

  Barry Allen : Make one what?

  Nora West-Allen : What if we can make a weapon more powerful than his weapon? Cicada can control his dagger, so what we would need would be something more powerful than his connection to it.

  Iris West-Allen : Wait, like... like some kind of supercharged magnet?

  Nora West-Allen : Exactly.

  Cisco Ramon : I don't know if we have anything strong enough for that. We made Sally out of a micro-composite alloy. As far as satellites go, she's... she was heavy-duty.

  Caitlin Snow : And even if we could get our hands on the dagger, we'd still have to figure out how to take the dark matter out to negate its powers.

  Sherloque Wells : Well, exactly right. I mean, what you're suggesting is we find an alloy... no, no, uh... indestructible alloy that has super magnetic properties but also has the ability to negate dark matter. I mean, where are we going to find such a thing?

  Nora West-Allen : The past.

• Nora West-Allen : You've already come across everything that we need, right? A strong alloy with magnetic properties.

  Cisco Ramon : Savitar's suit.

  Nora West-Allen : Something to remove dark matter.

  Caitlin Snow : The Speed Force transmitter that Zoom used to steal Barry's speed.

  Iris West-Allen : Yeah, but that was his Speed Force.

  Nora West-Allen : Yeah, but those are exotic particles, which are basically the same thing as dark energy, so we would just need some of that to recalibrate it.

  Ralph Dibny : Can... can you do that?

  Cisco Ramon : I mean, you'd have to infuse the transmitter with the same kind of dark matter.

  Ralph Dibny : Like the DeVoe kind?

  Cisco Ramon : More like the particle accelerator kind.

  Ralph Dibny : I'm sorry, we... we need to blow up S.T.A.R. Labs again?

  Nora West-Allen : No, no, not again. We just need to go back to the first time that it happened.

  Barry Allen : This is gonna mess with the timeline too much.

  Nora West-Allen : No, no, no. No, it's not. Savitar's suit, the transmitter, these are all just discarded objects in time, so if we steal them, it won't affect anything at all.

• Cisco Ramon : Okay, these are the best of times. Incidentally, they were also the worst of times, but in terms of going back, this is it. Savitar. When we defeated him, Barry phased into his suit, destroyed it, sending pieces of it flying far enough away that our past selves wouldn't notice if Barry took one or two pieces of it. What do you think?

  Caitlin Snow : Absolutely. Barry just has to get back into the Speed Force before the timeline catches up and those pieces get erased from existence.

  Cisco Ramon : [circling May 23, 2017]  I'm fairly optimistic.

  Ralph Dibny : Okay, what about the Speed Force transmitter thingy?

  Caitlin Snow : The night that Zoom injected the Speed Force into himself, he left the Speed Force transmitter in the viewing room.

  Cisco Ramon : [circling Aprijl 19, 2016]  Yes, that's brilliant. All he has to do is make sure no one's in there when he takes it.

  Ralph Dibny : What about when the particle accelerator exploded?

  Cisco Ramon : Well, right before everything went sideways, Wells was in the Cortex, and we...

  [remembering Ronnie] 

  Cisco Ramon : We were in the Pipeline intake.

  Caitlin Snow : That's the best time for Barry to go into the Time Vault. He can put a piece of Savitar's suit in the plinth and when the critical accelerator explodes, it should infuse it with dark matter.

  Cisco Ramon : [circling December 11, 2013]  Right. So, once that's done, we'll have all the pieces we need to make the device, we plant it in the hospital, the rest is history.

• Iris West-Allen : Everything worked?

  Nora West-Allen : Yeah.

  Barry Allen : Is Dwyer still at the hospital?

  Caitlin Snow : Hasn't left her side.

  Cisco Ramon : Did you plant the transmitter?

  Nora West-Allen : Yeah, we sure did.

  Barry Allen : Let's go get Cicada.
