Helios 685

Travelers
S01E06
Season 1 Episode 6

I like that they have an actual major event that they have to prevent because trying to manipulate a lot of little inter-connected things was starting to not make sense.

Especially considering the way they keep saying that no plan lasts once it makes contact with the past.

It also makes it better because there is no really no way to know what they are changing or if it will work. 

I can't believe the engineer didn't turn the key, did she think he wouldn't shoot her? What are they going to do if it didn't work?
