Did You Know?


Discussing Harry wearing the Thinking Cap, Cisco vows to pull him out before he "[starts] acting like Locutus of Borg and [starts] assimilating everybody", referencing to captain Picard from the Star Trek Next Generation when he was assimilated by the Borg. See more »


When Cisco and Joe are examining the vault door after Melting Point burned through it Cisco says the door was 10 inches thick and required 6,000 degrees to burn through it. Yet none of the money, which was laying out in the open no more than a few feet from the vault door, show no sign of having been exposed to such high heat. The money should have been burned up, or at the very least been greatly singed. See more »


[first lines]
Cisco Ramon: What if... What if I just, like, breach all three of the bus metas to, like, Earth-2?
Dr. Harry Wells: How about this? We alter each bus meta's DNA by performing intercellular surgery.
Cisco Ramon: And what? Turn them into chickens?
Dr. Harry Wells: Yeah.
Cisco Ramon: We're not Frankensteining innocent people.

Boring Filler
22 March 2018 | by xshanex-54161See all my reviews

This is one of those plot hole filled, unnecessary, mediocre episodes that's nothing more than filler. It has some moderately fun moments, but it's been the worst episode of the season hands down.

It wasn't painful to watch, but I was thrilled that it ended. Skipping it wouldn't matter in the least.
