Interesting question! My characters are not as interesting, lol!
Alec Tryon (CEO/farmer/Boomer combo): would light some candles and continue working/reading/something he deems 'productive' until he goes to bed--whenever that is...
Luke Tryon: Panic - if phone is almost dead, or continue sleeping. No other options to occupy him.
Aldi: Secretly a prepper, has spare batteries and a solar charger always on hand. But it's an old USB, only works on her 8 year old phone (she is like me, lol! Upgrades are for hive-minds, XD)
Carl: would continue to do chores at night. He thinks he can see in the dark. The bumps and bruises on his legs prove it.
My chickens don't use electricity (they somehow know how to use fire, so candles, coals, wood, any natural source of fuel)
Friar would probably continue what he does at nights, scribbling on his scrolls.
Bucky actually sleeps outside now, so he's none the wiser XD
Gallus (the top cock) might be concerned of his nightly patrols, but he'll keep on patrolling until the dawn.
Note to future self: This would be a fun idea to put in a future episode (centered on the humans, cause the chickens would be fine...unless there's a tornado/flood...)
