Big reveal! Not Nate is his son Jason! That certainly explains alot. Jason, after watching this episode, seems to be a better man than his father has become. That is why he seems to have a soft spot for Danny. The kid is just more humane.
Also, Neville keeps working to toughen up Danny I suspect in part, because he really does see the softness and weakness of his own son in Danny.
Charlie and company work to stop Danny from getting on a steam train to Philadelphia. Critics of the show have belabored endlessly the fact that the 15 year power outage exiles should be able to use steam. Voila! A steam train. The man working to get the train going complains that the train should be in a museum and it is unlikely to make the trip. Our Captain Neville tells him he can push it the remaining way to Philadelphia if need be.
We got a look at a map of the Monroe Republic:
I had feared that the little psycho had the entire nation but, though he has a large chunk he doesn't have it all. I suppose having this train will give his empire some oompf.
Charlie of course foiled everything by accidentally running into Neville in town as they were all split up looking for Danny, then following him in a lumbering, Charlie-determined manner. Shocker he noticed and grabbed her in an alley and stuck a blade to her neck. Cue Miles to show up and have a chat with his old buddy Neville.
In other developments, Nora plants a bomb on the train to blow up Neville and a bunch of officers in her duties as rebel. She works with the lone other rebel in town, a crusty old guy who has lost everything. At the last minute she decides, after looking mooningly at Charlie, that she made a mistake and can't blow it up with Danny on it. The old geezer wants revenge for his wife's death though, so he stabs her (causing me to briefly think, whoa, they're dispatching another character so quickly...but no just a teeny gut wound) to keep the train on the track to kablooie land.
This gives Charlie and Miles the opportunity to channel old westerns as they easily grab two saddled horses and take off after the train. Miles leaps train car to train car to get at the log, which he easily recognizes among the hundreds on the car and in the furnace. Reaches into the fire, grabs that exploding log out and tosses it just in time.
Charlie meanwhile spots Danny in the train car with Neville, plays peek a boo with him a couple of times before Danny decides to make his move. With Charlie locked outside whacking at the locked door handle barehanded he fights Neville (who had beat him bloody earlier in the episode for fun though Danny's lovely snoot shows no sign of a fight, no swollen lips or broken nose). Charlie gets the door lock off, pops in and lo, Jason aka Not Nate grabs her from behind. It doesn't matter where he came from, nope.
Despite the odds, both Charlie and Miles manage to escape and leap from the train, then watch it go away down the tracks.
Last scene: Charlie gives a rah rah "who is coming to Philadelphia" grumbly speech and moves out, clearly now the strong one and the group leader in the minds of the shows' writers. That's right guys, if you say this is the point at which Charlie has matured and becomes the decisive leader amongst bozos you intend her to be, then by gum we are buying it. Absolutely. My heroine, yo.
