Naw. Chalky ain't getting killed. They wouldn't have introduced the BLACK CLUB on the Boardwalk scenario if he was. That's gonna be a plot for Season 4. I think Gillian might survive, they kind of need a strong female antag/protag so she might be safe. I doubt they kill Harrow -- they saw all the backlash with Jimmy, don't think they want to lose another fan favorite.
I have a bad feeling Eli is gonna get killed or maybe his son. They might kill Eli's son to build a wedge between Nucky and Eli going in season 4.
perhaps. i would think he gets his son out of the line of fire tho, since it looks like a day or so passes judging by the previews. i could see eli taking a bullet and dying for nucky to make up for trying to kill him season 2. since u see them walking up the stairs together guns drawn i can see that scenario playing out.
and take anyone, take the kids, just leave harrow alone.
