Children of Earth : Day Two ( TV story ) Children of Earth : Day Two was the second episode in the third series of " Torchwood " . It was significant for showing the extent of Jack Harkness ' regeneration ability , as he survived being blown apart . Synopsis . Torchwood Three has been blown up by a bomb planted in Jack Harkness . Gwen , Rhys and Ianto are on the run . Can they elude the government and save the planet from the 456 ? Plot . The Hub has blown up . As Gwen emerges from the rubble she is seized by an assassination squad and is dragged into an ambulance . The men pin her flat on a stretcher . One prepares a needle , but they let go of her when she bites one of them . Leaping to her feet , Gwen drives off in the ambulance with one of the men . Holding him at gunpoint , she is told that the government has ordered the destruction of Torchwood but he doesn ' t have any further information . He goes for a gun but she shoots his foot , leaving him there , taking his pistol as well . At the explosion , Johnson arrives as does Andy Davidson with the police . Johnson surveys the area , understanding they need to ensure Gwen and Ianto are dead . Andy , hearing Gwen ' s name , interjects she is not a threat . Johnson , realsing Andy knew her in the police , forces him to escort them to her house . Gwen makes it home and hurriedly wakes Rhys telling him what has happened and that they need to leave immediately . Just then she gets a call from Ianto , who has also survived , and tells him what she has learned . Neither can understand why the government has ordered their deaths ; however they cannot set up a meeting point as the phones have likely been bugged . Gwen is forced to leave when the assassination squad show up . Andy ensures Gwen is not worth the trouble just as Gwen shoots out the tires on the squad ' s vehicle . Johnson counters Andy ' s statement , given what Gwen just did . However , Andy notes she shot the wheels , evidently not intending to harm then . Meanwhile , Gwen and Rhys drive a short distance away before dumping the car . Gwen insists they must go on foot now as cars are traceable with the license plates ; they are now rogue agents . The next morning , Johnson finds Jack Harkness ' remains in the ruins of the Hub , little more than an arm and a head . They are taken to a warehouse in London . His body begins to reconstruct itself . Meanwhile , Ianto sends a card to his sister through their newspaper , asking her to meet him at the park where his leg was broken as a child and to bring a laptop computer . Her son David knows Ianto left it and warns her they ' ve probably been bugged . Typically , a car with two government agents is parked in the estate , and the men are listening to their conversations . Johnny decides to get back at the men by making them listen to obnoxious things , such as how David " pissed the bed " after the raid last night . Micah taunts his humiliated brother while he objects that his dad is lying . Rhiannon gets annoyed and goes upstairs to read Ianto ' s message , soon joined by her husband after he drops the vulgar act . Meanwhile , the body bag containing Jack ' s remains is now filled with a skeleton and muscle s , as opposed to the few pieces of flesh from the explosion , showing that his body is regrowing . Gwen and Rhys find that their bank accounts have been frozen , and with nowhere else to go decide to head to London as that is where everything is happening . The two sneak aboard a lorry , which is full of potato es ; during the trip , Gwen tries to announce her pregnancy to Rhys and lets him figure it out through her body language . He is excited to learn about their future child , but the thought of letting Gwen endure this danger while pregnant upsets him , and he expounds the reasons for him to stick with her while she ' s on the run . At around the same time , Jack ' s body has halfway completed regenerating , but his outer skin is still burnt , raw , and unformed , nor can he see . He has recovered enough to regain conciousness , and immediately bellows out in mind - numbing pain with a primal scream . One of the special force agents notes how horrifying Jack ' s immortality is as Johnson watches , disturbed . Later on that day , Johnny cleverly rounds up a posse of children from the estate and they surround the agents ' car . He accuses them of snooping , and when they deny it , he deems them perverts and rallies the kids to get the " paedos " . The group swamps the vehicle and rocks it aggressively , obstructing the agents ' view out the car windows . Given the unfriendly neighbourhood , this creates a believable and convenient distraction for Rhiannon to drive away unnoticed . Rhiannon meets with Ianto in a park and discovers he has been wounded by the Hub ' s explosion . While they speak , the kids in the park , along with the rest of the children in the world , suddenly stop moving again and declare another ominous message ; " We are coming tomorrow . " Ianto approaches a girl in the park after the kids return to normal with the intent of learning what she felt during the moment she froze , but gets rebuffed by her protective mother , who thinks he ' s doing something perverted . Ianto gives up on the kids and requests Johnny ' s car and his sister ' s laptop so he can track Jack down . In London , Gwen tries to contact John Frobisher . Her call is taken by Lois Habiba . At MI5 , Frobisher , Bridget and Lois see an unknown device being built by Mr Dekker to the 456 ' s specifications . Lois meets with Gwen and Rhys and tells them it was Frobisher who issued the kill order on Jack and several others . Gwen recognises none of the names . The three meet up at a chippy where , after eating , Lois also gives Gwen information about the compound where Jack is being kept . She also suggests a way for Gwen and Rhys to gain entry . Jack , now fully re - formed and no longer in acute pain , is sealed in concrete by Johnson to prevent his escape , who pragmatically refuses to reveal any information to him because he remains alive and a viable threat , which is why she has chosen to keep him contained . Gwen and Rhys , as Lois had suggested , pose as funeral directors come to fetch Rupesh Patanjali ' s body , also held at the compound . Their plan initially works . The soldier who requested the retrieval , Camara Kodak is friendly and does not suspect Gwen or Rhys to be imposters . Rhys gets defensive when he flirts with his wife and lets him figure out they ' re a married couple . It doesn ' t give them away , but Gwen is unhappy with Rhys ' s slip of the tongue . When the group enters the cell with Patanjali ' s body bag , Gwen disables the camera surveillance with the same pen she used in the mental care facility , then pistol whips Kodak to the back of the head while he isn ' t looking , rendering him unconscious . Gwen snatches his keys and locks the guard inside the cell , while she and Rhys start opening the next one . Their disabling of the hallway camera attracts the suspicion of the guard watching the security footage . The second cell turns out to hold the body of the undercover soldier who was shot by the sniper attacking Gwen . When she disables the camera in this cell , the guard at the desk sees the act perpetrated and sounds the alarms . Not willing to waste time on Rhys finding the key for the third lock , Gwen breaks it open with several gunshots , only to find it blocked by a concrete slab . The soldiers in the compound surround Gwen and Rhys and open fire . Gwen empties her gun defending herself and her husband as he declares they ' ll have to surrender , while Johnson calmly marches forward with a patrol unit to corral them . Gwen discovers it was a mistake to waste her limited ammunition on the cell lock — her gun is out of bullets . Cornered , she lowers her weapons and kneels to the floor . The room quakes and a pile of rubble begins falling from the ceiling as the concrete wall is forcefully yanked out of the wall . Ianto , who has also arrived in London and learned where Jack was taken , has stolen a forklift . He lifts Jack ' s cell and pulls it out of the compound . Gwen and Rhys escape with Ianto in the forklift , chased by Johnson and many soldiers . The forklift isn ' t fast enough to outrun them . Gwen pulls out her other gun and returns fire at the men shooting at the trio , Rhys ducking for cover . They find themselves blocked by the cement truck used to pour concrete in Jack ' s cell . Rhys hops out and drives the truck out of the way , then Gwen turns it into a barricade by shooting its gas tank , igniting the vehicle and allowing the group to get away without being pursued . Johnson informs Frobisher they have run into a roadblock . He replies that they cannot let the Torchwood personnel escape and tell someone of the situation at hand or they ' ll be on the chopping block . Ianto drops the concrete block into a quarry where it breaks apart , releasing Jack . He revives and stands up , unclothed and covered in bits of mud and concrete . Rhys offers him the coat from the funeral director ' s suit , and Gwen hands it off to him while trying not to stare at his nude body . Jack reunites with the group and learns about the message the children have spoken . Torchwood Three departs in Johnny ' s car to figure out their next move . Back at the MI5 headquarters , the mysterious device is completed : a sealed , glass - walled chamber filled with a concoction of gases poison ous to human s . Frobisher , Spears , and Decker contemplate its purpose . Bridget wonders what could possibly live inside that gas , but Dekker informs her they don ' t have time to figure it out with the 456 arriving tomorrow . Frobisher indicates only Britain knows about the 456 ' s contact with Earth and their return will not concern a global level . Dekker sees that the room for the 456 is like an ambassadorial suite or throne room . As his colleagues walk out of the room , Dekker huffs on the glass walls and embraces the tank with an unnatural sense of welcoming anticipation .
