- "It's snowing, right? Where are we, upstate?"
"We're five miles outside of Rose Hill, Tennessee."
"Why?! J.A.R.V.I.S.! Not my idea! What are we doing here? This is thousands of miles away, I gotta get Pepper, I gotta..."
"I prepared a flight plan. This was the location."
- ―Tony Stark and J.A.R.V.I.S.[src]
Rose Hill is a city in the state of Tennessee.
Explosion of Chad Davis
Chad Davis was offered to be a test subject for Extremis Program developed by A.I.M., under Aldrich Killian's direction. Davis ended up being unable to resist the side effects of Extremis, and spontaneously exploded in his hometown of Rose Hill, killing five other people. The explosion was covered up as a suicide, blaming Davis for the death of the five victims.
Arrival of Tony Stark
Tony Stark investigated the terrorist attacks of the individual known only as the Mandarin, believing him responsible for the explosion that almost killed Happy Hogan in Los Angeles. During the investigation, he discovered an event with many similarities to the identified terrorist attacks, the use of an explosive for the suicide of Chad Davis in Rose Hill, with J.A.R.V.I.S. calculating a flight plan to Tennessee, in order to further investigate the event.
Following the destruction of Tony Stark's Mansion at Malibu, J.A.R.V.I.S. sustained damage and followed the last programmed flight plan, taking an unconscious Stark to the outskirts of Rose Hill, where he recovered consciousness upon crashing. J.A.R.V.I.S. suffered damage during the attack, and was not able to explain to Stark the reason he had to follow the flight plan.
Stark, stranded alone in Tennessee, had to carry his depowered armor until he found a gas station, where he obtained some clothes to keep himself warm, and called Pepper Potts to let her know he was alive, and to apologize for putting her in danger.
Stark took refuge in a garage, where he started fixing the chips implanted into his arm before beginning to repair his armor. Harley Keener, the owner of the garage, appeared and demanded to know who Stark was, not recognizing him until he saw the Iron Man Armor, and informing Stark that the press believed him deceased following the attack on his mansion.
Tony Stark went to visit the memorial site for the victims of the explosion caused by Chad Davis, accompanied by Harley Keener, who tried to ask Stark about the event of the Battle of New York and about the Avengers. Keener explained what was thought to happen the day of the explosion, as it was thought that Davis committed suicide using a bomb.
Stark realized that although there were six victims of the explosion including Davis, their remains only left five shadows in the wall. The explanation given is that those shadows represented the souls of the innocent victims as they went to heaven, but Davis' soul was condemned to hell.
Keener tried to ask again about the events at New York City, but Stark asked him to stop, as he didn't liked talking about it, as he suffered anxiety attacks when remembering the events. Keener's continuous questions prompted another anxiety attack on Stark.
Battle of Rose Hill
Tony Stark went to a local bar to find Mrs. Davis, but before entering, he came across Ellen Brandt, noticing the scars on her face, and after a brief chat, Brandt departed pretending not to know who he was.
Stark found Mrs. Davis and asked her what happened with her son, but Mrs. Davis gave him the file she thought he was looking for. Stark deduced Mrs. Davis was waiting for another person, and when looking through the file, he saw that Chad Davis was related to Jack Taggart, involved in another explosion in Los Angeles. Stark quickly revealed that Davis' death was not a suicide, as it was used as a cover.
Ellen Brandt reappeared, revealing herself to be the person who called Mrs. Davis, pretending to be an agent of the Homeland Security Department and proceeded to arrest Stark. The Rose Hill Sheriff demanded to know more about the arrest, and when Brandt's excuses about jurisdiction did not convince him, Brandt simply killed the sheriff using her Extremis derived powers.
Mrs. Davis hid the file, convinced by Stark's words, and Stark ran when he watched that Brandt was not a federal agent. On the street, Stark came across Eric Savin, who tried to shoot him, and only Harley Keener's intervention saved Stark by making him miss the shot.
Stark hid from Brandt at an establishment, but she managed to catch him by surprise, and as Stark realized a hand-to-hand fight was not going to stop her due to Extremis, Stark caused a fire inside the building. Brandt was able to step through the flame, but that gave Stark time to improvise an explosion using a set of military badges inside a microwave. The explosion launched Brandt to a set of power lines, killing her.
However, Eric Savin destroyed a water depot, trapping Stark under the debris, and took Harley Keener as a hostage to obtain the file about Davis. Stark told Keener to use the weapon he gave him to use against bullies, a flash grenade, and seized the opportunity to attack Savin with a concealed repulsor from his armor.
Thinking he killed Savin, Stark stole his car and obtained the file about Chad Davis. Keener approached Stark for saving his life, and asked him to take care of the armor and stay close to the phone if he called him. Stark apologized for his rudeness before leaving the town, and while Keener tried to make him feel guilty for abandoning him, Stark realized it was trick and mocked one of Keener's early quotes as he left.
Meanwhile, Savin regenerated from his wounds.
Tony Stark investigated Aldrich Killian and learnt how he used injured veterans from the United States Armed Forces as candidates for the use of Extremis, and its side-effects can end up in explosion, and believed the Mandarin was the buyer of Killian's Extremis research as a weapon.
J.A.R.V.I.S. tracked the Mandarin's broadcast signal using available A.I.M. downlink facilities, and though Stark tried to guess the location mentioning logical places such as the Far East, Europe, North Africa, Iran, Pakistan or Syria; J.A.R.V.I.S. revealed that Miami was the origin of the broadcast. Stark believed it was one of the failures with J.A.R.V.I.S.' speech drive, and asked Harley Keener to read the real location on the screen, signaling that J.A.R.V.I.S. was right, and Miami was the actual location.
Stark asked about the status of the armor, and suffered another anxiety attack when he realized the armor was not ready, as the energy source was not suitable, and maybe it could not succeed in revitalizing the armor. Harley Keener tried to comfort him, and gave him an idea to build other weapons. Upon the realization, Stark managed to calm himself, and went on to buy everyday items to build a series of hand-made weapons.
Departure of the Armor
The following morning, Harley Keener witnessed how the different pieces of the Iron Man Armor kept inside tried to open the door as they had been summoned by Tony Stark in Miami. As they were unable to exit, Keener opened the door and saw how the armor flew to Miami.
A Gift from the Mechanic
Tony Stark showed Harley Keener his gratitude for his assistance during his stay at Rose Hill, sending him a series of gifts stored into Keener's now redesigned garage, such as a computer, another limited edition watch as the one Stark borrowed, a replica of Dum-E and a new potato gun.
