Roy is travelling to the outskirts, hearing a rumor from a contact of his about a man called Joseph who lives faraway into the desert. It turns out that the old man who was Bill's companion is indeed Joseph. Roy comes into his home, and asks Joseph if he has seen Solty which confirms.
Joseph explains that many things went around while Solty was living in his farm, but right now she has left to return to her home.
Later that night Joseph and Roy sustained a long conversation.
I will appreciate your help JShaggy or anyone else who has Japanese comprehension skills to understand what exactly did those two discussed.
Rally formally introduces Rose Anderson as the new RUC department chief who Integral, Silvia, Celica, and Axela will be addressing to. Rose's personality is exactly the same, as she's making herself home at RUC like she did at Roy's apartment before. It's bluntly obvious, given Silvia's crush on Rally, that objects to Rose being her superior and sustains that the latter (Rose) is a wanted criminal.
Rose, nevertheless, cares little for the Sylvia's heated crush and everytime that Axela or Integra address her by the title of chief Rose becomes upset and asks them to call her simply by Rose.
Solty has returned to Roy's apartment but found no one inside.
RUC undergoes a mission involving the capture of three criminals hiding inside an abandoned store. With her awestruck sniper skills, Celica effortlessly disables the resemble arm of one of the thugs. While the second thug attempts to escape via a backdoor, Sylvia violently storms in to arrest them. However, the second thug, who has resemble leg prosthetic, puts resistance and begins to trade kicks with Sylvia, but she blocks with no problem.
The injured thug calls to their female partner, and she throws a flash bomb illuminating everything inside.
Celica cannot shoot because of the blinding light that nullifies her vision. Rose, who accompanied the RUC girls as sort of a supervisor, is pretty much pissed off about the RUC agents lack of proactiveness in their methods and calls Celica out of the mission.
Sylvia has it hard to deal with the second thug, but all resistance ends when Rose makes her entrance and shoots the resemble parts of the thug with fairly ease, then she immediately goes after the woman thug and subdues her in no time.
The woman thug knows who Rose is and shockingly asks what she's doing as is supposed to be a same thief like them. In her usual frivolous demeanor, Rose cooly answers that she's RUC agent Rose Anderson.
There's something fishy about this new Rose. Her personality is unscathed, however, her memories are either swayed or scrambled for good.
Solty appears in Miranda's office. She's quickly tackled by Kasha who starts crying because of how concerned she has been for Solty having left. Yuuto's been also worried about Solty's departure in his usual self but is quickly cut shorted by Kasha, calling him hentai for nearing Solty.
Miranda informs Solty that Roy snapped of his fury, and he too went to look after her.
After beating the crap out of Yuuto with some wrestling moves, Kasha comments on Solty's sweaty scent and takes her to take a shower both. In the shower, kidding or not, Solty comments to Kasha that she's seem to found a precious person for her. Yuuto is eavesdropping the whole conversation behind the closed door and crying out of jealousy, but is quickly found out by Miranda who berates and then slaps him.
Back at RUC HQ, Sylvia, believing being ridiculed by Rose's skills during their mission, challenges Rose to a duel to display their capacities which Rose accepts.
Both of them put on the RUC suits and issue a rule for only full contact blows.
Rose wearing the RUC suits!! About time! 
The first round goes to Sylvia immediately attacking Rose with quick punches and kicks, leaving Rose no room to defend herself. Celica comments on how amused it is the fighting as Sylvia has finished it quickly. However, Rose is not impressed just flattered and takes now her turns. Indeed, Rose puts on an stunning performance on her suit which quite shocks all the four girls.
The data for Rose's suit is going overload and starts to dodge/attack Sylvia with relative easiness turning tide towards her favor. Rose manages to kick Sylvia's butt and just before delivering the final blow, Rose stops at merely an inch of connecting her fist on Sylvia's face. Rally witnessed the match on the other side of the hall, rooting a mischievous grin for Rose.
Rose puns on Sylvia if wants to continue, but the latter forfeits the match.
After the match, the other three girls try to comfort Sylvia, but she displays remarkable self-composure and leaves saying that she's fine. Once alone Sylvia cannot hold her tears due that Rose has humiliated her.
That same night, Axela tries accessing the command room, but her key card is not responding. She learns from the officials that her privileges had been revoked ordered by Rally. Axela eavesdrops a conversation that Rally sustains with Rose, which quite shocks her.
The next morning, RUC announces that Celica has been fired. She and her teammates cannot believe what's happening. Sylvia immediately takes a negative stance against Rose for all of this, however, Rose quickly objects that she has nothing to do with this.
Sylvia decides to cut the chase and going straight to the point, that is Rally. Axela tries forcefully to persuade Sylvia not to go and argue against Rally but is futile.
Sylvia meets with Rally at the hall center and engage in a long conversation, starting with Sylvia objecting about Celica's dismissal. However, Rally makes quick work with his words which quite make an effect on Sylvia as she becomes slightly smitten.
On a sudden and cruel twist of fate Rally's personality makes a 180 degree turn.
As he was comforting Sylvia on his arms, he stabs her on the gut with his left arm. A blatantly shocked Sylvia asks why as she admired him. In cold, insane fashion Rally replies that all he needs is Rose, therefore, he does not needs of her.
Hinamori-Aizen incident
Sylvia falls to the floor motionless on a puddle of her own blood. Rally's left arm is a Resemble.
Celica, Axcela, and Integral come in to check what was going on, witnessing Rally standing aside from a seemingly dead Sylvia.
Rally immediately orders them to shut up in quite violent manner and tells all of them that are fired.
