10 days. Darkness

If these kids have been in tunnels most of their lives (or all), without proper sunlight or oxygen, Patriots can't bring them out mid-day; it MUST be done at night! "Darkness" Nighttime "stay at home" orders so civilians don't see the movements. 10 day rescue

They wouldn't be able to handle sunlight right now, and taking them straight to "mercy" and "comfort", they can be cared for in controlled lighting without windows. They can slowly acclimate them all with sunlight this way.

Also, think of how terrifying it will be for these kids coming up to a world they never knew existed. Could this have to do with the stay at home orders as well? Think of how much more petrified they would be to come out to a bustling city vs. now where it's 'quiet'. #SaveTheKids
