Nikita: Renting a car could be risky, we need proof of identity.

Pavel: Yeah, let's see what we can do with this train system map.

Nikita: You should visit location 6 first, then 8, then 1.

Pavel: You'll take the remaining 5 locations?

Nikita: Yes, I'll visit locations 2, 5, 7, 3, and then 4.

Pavel: That's the most efficient but what about the surveillance time?

Nikita: If we spend 1 hour at each location, this could change the most efficient path.

Pavel: Yes, because some trains get very busy during the day and at night.

Nikita: Hmm, maybe a 3/5 split isn't the best option...

Pavel: A 4/4 split could be better.

Nikita: I think the best path for you is 4-1-6-8.

Pavel: Yeah, that's what I was thinking. I need to get location 4 out of the way first.

Nikita: To get home, you need to pass through location 1 again. You have to pass by the same location twice...

Pavel: If we spy correctly, it shouldn't matter if they see me later in the day.

Nikita: I'll take the path 2-5-7-3.

Pavel: So, how long will all of this take?

Nikita: I'll do the calculations, one moment.

Pavel: Gotta stay sharp, Nick! I'm timing you!
