Anthony's nerves are going to be somewhat fried for the blackout period even by their usual standards, and he's going to be well-aware of it on the whole - and though the ghosts are probably going to like him for it, he's likely going to try to avoid actively acknowledging them as much as possible until it's confirmed to 'im that it's most definitely not just him.

Also, what with Nick persisting with his making use of his inside-man position there, he is going to be keeping up with affairs related to the garage, but whatever he'd do or to whatever extent he might attempt to get involved is uncertain!

Bill is boarding the spaceship and getting put-off by the ghostly presences - and with reminders that there's still fishiness lurking around in Locke with a presence that can be felt, he's going to push on into getting involved with things even beyond the meeting. He'll also likely opt for the garage assault over the compound infiltration.

Steve is gaining his first ability from the blackouts, and it's a troublemaker's ability. Namely, he can toss fireballs - he'll probably show it off and look into its applications before getting bold and attempting to play chicken past the compound barrier, with or without someone to watch his back/make a challenge of it, but that's certainly undecided!
