Cisco, Julian and others in “Unfinished Business”

Cisco

You know that thing we used to talk to Savitar?

Julian

Yes.

Cisco

[points to the headset] Meet the Electrode-Halo. So basically, these two are linked electromagnetically via Goldtooth.

Julian

"Gold-tooth"?

Cisco

[pleased with himself] Yeah, it's... kinda the Cisco Ramon inter-dimensional equivalent of Bluetooth. Kinda proud of it. Anyway, it gives us all the relevant locus information no matter what corner of the Multiverse Barry's stuck in.

Caitlin

And, if Barry needs our help, it stimulates Cisco's prefrontal cortex.

Cisco

Then I'll open a breach and pfff... siphon them back in.

Julian

Good lord. Multiverses, breaches, halos. Easy bloody peasy.

Cisco

By George, I think he's got it.
