Tim has been Robin for two months, and Bruce has enjoyed having someone to work with, however Tim isn't accompanying him on this mission tonight. He's currently trying to track down world famous assassin David Cain, who he has learned was hired to assassinate Jim Gordon.

He's been trying to get a hold of Jim to tell him, however he hasn't picked up yet. It doesn't help that his relationship with Jim has been strained ever since the paralyzation of Barbara, however he cannot let his personal life bleed into this.

Leaping across another building, he taps his fingers to his cowl, "Barbara?"

"Bruce? What do you need?" the voice asks on the other side of the line.

"Barbara, would you happen to know where your father is currently. I've been trying to get a hold of him for over an hour," Bruce explains to her, a hint of concern coated in his voice.

Picking up on this, Barbara replies, "He's at my apartment, why is something wrong?"

Quickly, Bruce changes paths, and heads toward Barbara's apartment on the other side of town. "Barbara, I'll be there in a minute, get your father away from any windows immediately," he commands. Pressing a button on his gauntlet, the Batmobile comes flying down a back alley. He jumps off the roof, landing in the car, and steps on the gas.

"Why? What's wrong?" Barbara asks, panic evident in her voice.

Bruce swerves around another car, accelerating even more. "I'll explain when I get there."

He continues speeding up until he has Barbara's building in sight. He launches himself from the car and glides to her apartment, landing on her terrace.

She sees him and opens the door, so he can enter. "C'mon, we have to go," Bruce tells Barbara and Jim who is just now aware of his presence.

"What the hell are you doing here?" Jim asks Bruce as he moves toward him.

Grabbing Jim's arm, he tells him, "Someone is trying to kill you. I'm going to stop them, but first, I need to get you somewhere safe."

Getting up, Jim looks at Bruce's white eyes. "Slow down, who's trying to kill me? And why are they trying to kill me?"

"An assassin trained by the League of Assassins named David Cain. He is one of the top assassins in the world," Bruce explains. "I found out when…" However before he can finish, a athletically built man with white hair crashes through the window. He throws a knife in the Commissioner's direction. Bruce catches the blade, just before it hits Jim.

Cain pulls out a sword, and begins slicing at Bruce. He swings precisely and quickly, giving Bruce a run for his money. And while Bruce was able to dodge all the attacks, several almost hit him.

Bruce takes the offensive this time, and throws a punch at Cain's face, which he catches. He goes to flip Bruce, who lands and in turn flips Cain, who lands as well. The two circle each other, before Cain decides to attack once more. He slices at Bruce's stomach, which Bruce dodges, but knocks into a table because of.

Due to his lack of balance, Bruce is barely able to block the punch that Cain throws at his abdomen. However, he isn't so lucky with the next strike that Cain throws at his temple.

Barbara reaches for a secret switch on the side of her wheelchair, which releases two batons. She throws one at Cain's head, which he moves out of the way of.

He prepares to attack Barbara and Jim, when a small figure in all black, rushes in and tackles Cain to the ground, and quickly getting on their feet. Cain acts as though he recognizes the person, and almost relaxes slightly. "Get out of my way," he commands.

"No," the female figure responds. Cain's eyes widen at the words spoken by the figure. In his moment of confusion, the figure jumps up and strikes Cain in the chest.

The figure strikes with such force, that Cain is winded enough for them to continue the attack, without Cain doing anything. The figure throws a flurry of punches at Cain's abdomen. The figure finally delivers a heavy hit to Cain's head.

Stumbling back, trying to regain his footing, Cain decides it'd be better to attack later, and dives out the window. The figure seeing his retreat, dives out the window, trying to follow him as well.

"One of yours?" Jim asks confused, as Bruce gets up from the ground.

"No," Bruce answers just as confused, if not more so, than Jim.

Eying Bruce, Jim asks, "Then who the hell is she?"

Looking at Jim and then at the window where both Cain and the mysterious figure dived out, Bruce responds, "I have no idea. But I intend on finding out." He turns around and examines the window for any evidence. He sees some blood on the window, from someone cutting themself when they entered or exited. Taking out a vile, he let's the blood drip in it so he can examine it at the Batcave. "Okay, c'mon Jim, you're coming with me. You too, Barbara."

"I'm not gonna argue," Jim tells him, grabbing his coat and wheeling Barbara toward the door. He opens the door and pushes Barbara through the opening.

When they get down the elevator and out the entrance, they see Bruce standing by the Batmobile. "Here," he says, helping Barbara into the Batmobile. He puts the wheelchair in the back, and Jim gets in as well.

Bruce gets in and starts the car. He presses a button and autopilot is initiated, as is a blackening of the windshield so Jim couldn't see where they were going.

When they arrive back at the cave, Tim is waiting for Bruce in full uniform. "What happened?" He asks when he sees both Jim and Barbara getting out of the car.

"An assassin targeting Jim," Bruce explains walking over to the Batcomputer. He sits down and starts examining the blood sample. First he cross checks it with David Cain's DNA to see if it's his, however something unusual happens.

"Wait…" Barbara says looking over Bruce's shoulder. "Does that mean that the girl who saved us was his daughter?"

Tim looks at them with a raised eyebrow, "Someone saved you guys?"

"Someone assisted me in fighting David Cain. They seemed to be familiar with one another, however I wouldn't have suspected them being father and daughter," Bruce explains to Tim.

The chair slides back as Bruce begins getting up. "Where are you going?" Tim asks.

"I'm going to go find David Cain," Bruce tells him as he walks over to the Batmobile.

Tim runs over and hops into the Batmobile, "I'm coming!" Bruce eyes him, then starts the car and drives out of the cave, leaving Barbara and Jim.

After driving around for an hour, Barbara's voice comes over the comm, "Since Agent A isn't currently here, I thought I'd be of use. Anyway, I saw Cain in security footage from GCPD about five minutes ago, he should still be in vicinity."

"Okay, thanks Barbara," Bruce replies, take a turn down an alley. He steps on the gas and speeds off toward GCPD.

The car slides to a stop, Tim and Bruce jump out and grapple to a vantage point to see if they can spot Cain. They don't see Cain, however they do see the figure from before, his daughter. So, they jump from the vantage point and glide to her location.

When they get there though, they realize it was a trap when they see that his daughter is tied in place. Before they have time to react, Cain comes out and elbows Bruce in the back of the head.

Tim reaches for his bo staff, but it gets knocked out of his hand before he can use it. He swings at Cain, but Cain easily moves out of the way of ever punch he throws. However, that was a distraction, and while Tim was throwing punches, he threw a batarang at the rope holding Cain's daughter in place.

His daughter realizes this, and uses it to cut herself free, while Bruce and Tim fight Cain. Bruce swipes at Cain's legs, while Tim throws a punch at Cain's chest. Cain's legs are hit, and he loses his balance, allowing Tim's punch to land.

Cain grabs a knife and throws it at them, however, his daughter catches it. "Cassandra, STOP!" He shouts at his daughter.

"No… you… stop," She tells him unsure if she said it right, but still meaning it. He gets up and begins swinging violently at her, but she easily dodges every blow, knowing his moves before he does.

Seeing the way he slightly tilted his head and bent his knee, she knows he's going for a quick jab in the abdomen. She catches the punch and kicks at his knee, knocking him to the ground. Then she throws a quick strike to his head that knocks him out.

"Thank you," Bruce says offering his hand to Cassandra. She takes his hand and shakes it. "You're welcome to stay with us if you have nowhere else to go," Bruce offers to her gently and kindly, as he ties up Cain. She nods with a small smile, and follows him to the Batmobile.

They first quickly let Bullock know that they left a world famous assassin on the roof, and then begin driving to the Batcave. When they get there, Barbara is still at the computer as is Jim.

They hear the Batmobile, and Barbara and Jim go over to Bruce and Tim and notice that Cassandra is with them. Barbara wheels over to Cassandra and hugs her, "Thank you for saving my dad." Cassandra seems taken aback by the gesture at first, but gives into it.

"What's gonna happen to the girl?" Gordon asks Bruce, while Barbara hugs her.

Bruce sighs, "I don't think she has anyone Jim… I can't let her be on her own, I have to take her in."

Jim chuckles nodding, and pats Bruce on the shoulder, "I'll discreetly help make it official that Bruce Wayne adopted a young girl." Bruce looks at him shocked for a minute. "C'mon, I've worked with you for a decade. What kind of cop would I be if I couldn't figure that out." Jim yawns, "If it wouldn't be too much to ask, could you drive me back to my house now?"

"Sure, Jim," Bruce tells him.
