I'm glad we got to team up.

- Ladies and gentleman,
say hello to the tachyon absorption enhancer 2.5,
now complete with completely recalibrated
Time Bureau technology.
- We haven't tested it yet, but it should counterbalance
the negative tachyons in Nora's cells.
- Here you go, Billy Pilgrim.
Consider yourself unstuck in time.
- So I can run home now?
- Or...
maybe we hit pause on this thing.
- You want Nora to stay?
- Um, yeah, I thought
getting her home was our priority.
- No, it is, I just--
now, I'm thinking that maybe we should make sure
her powers are working correctly
before we send her home.
- And what about the timeline?
- It's risky, but I don't know.
I mean, Wally and I were talking about it.
- Yeah, the Legends have a theory.
Uh, there are some historical events that are soft.
Basically, you change those,
it's not going to affect much else,
like catching Gridlock late.
And then, there are those that are fixed.
You mess with them, and all sorts of craziness
starts to happen.
- Like the night my mom died.
Changing that created Flashpoint.
- It looks like Nora is gonna need a place to stay.
- Uh, yes, and I'll stay in the lounge.

But you didn't finish what you set out to do,

Besides, if he did that, who knows?

Kidding. I'm glad you're here,
