"You knew and you didn't tell me?" Lee shouts at Jack as he sat at his desk, quiet.

Gwen retrieved Lee and debriefed him on what's really going on and rightfully, Lee's upset with Jack for keeping him in the dark. He hadn't a chance to even change out of his uniform when Gwen called him and told him that he's being recalled to the HQ.

"You don't understand, Lee, I was only doing it for your sake," Jack tells him.

He never wanted Lee to find out because he worried about Lee getting himself hurt or worse trying to stop Vena on his own. If he could've told Lee the truth, he would have, and wouldn't mince the words.

"I thought we were a team!" Lee pointed at him.

Nodding, Jack said they were, but he pointed out that he had to do what he did to keep Lee safe and out of harm's way.

Lee retorts, saying that it seems Jack's plan didn't work and that people died and one almost died.

"Lee, what would you have done if I told you then?" Jack sharply asked him.

He wanted an answer from Lee.

Pacing around the office with a look in his emerald eyes, Lee said he probably wouldn't believe them and when he saw the murders and put two and two together, he probably would've tried to find her.

"Lee, she's not human anymore, we've ran tests on what we gathered. The last thing I needed is you trying to tell yourself she is," Jack raised his voice. "I'm supposed to keep my team safe and I can't have you thinking you can save her. We've considered all options and they're unavailable."

Bringing up the mutations, Jack warned that Vena might not see Lee as her former boyfriend and instead a walking food cart. She's having no qualms attacking anyone at this stage.

"Well, what about that man you brought in, what was it, the Doctor, can't he do something?" Lee pointed behind.

Jack told Lee that the Doctor (Matt) couldn't do much, either. He's here because they needed his help.

Lee asked what good is the Doctor if he can't help turn Vena back and Jack told him in a low voice, "Because he's going to help us kill her."

Before Lee opened his mouth, Matt stepped into the office, looking out of place as he noticed what appeared to be a beautiful young lady with blonde hair tied up in a bun, natural shaded makeup, and a black sleeveless dress that went down to her knees.

"Oh, Doctor, speaking of the devil," Jack diverted attention to him.

Matt looked at the woman and stunned when Jack told him that's Lee and Lee said he hadn't the chance to take off his costume.

"I… uh…" Matt's baffled.

If he didn't know this and Lee never spoke, he'd think it's a woman.

Jack reminded Matt that Lee's a cross dresser by trade and it caught up to him.

"Oh, sorry," Matt apologized for not noticing sooner and Lee shrugged.

Lee wouldn't be doing his job if someone noticed he wasn't really a woman. Part of the act.

Having a slender build helps with the illusion and Lee wasn't surprised Matt didn't catch on until Jack told him.

"Getting back to the situation at hand, we have to act now, Vena's changing by the night and I don't want to know what she looks like at the end of the week," Jack got their attention and their minds back on the subject at hand.

Given the descriptions Ianto and Ripley gave about Vena, it's evident that she's changing into something else and what the end stage of that is, Jack didn't want to know.

"Someone reported blood spots near a freighter, she might be in the warehouse nearby," Jack informed them of the discovered blood from Ianto firing at Vena the other night.

He made sure it's Vena's blood by comparing it to the blood they have on file and it's not looking good. Barely a match, the DNA changed further from the last blood drawn.

By the time they finally kill her, there's no doubt in Jack's mind, there'll be nothing left of Vena, just a creature with her name, nothing more.

"What do you propose we do?" Matt crossed his arms as he asked Jack what he expected them to do.

Baiting doesn't seem to work and Vena's unpredictable when she wants to attack. Not to mention, it's impossible to get close to her without her mauling them.

Frowning, Jack said that the only other option's incineration. Trap her in the warehouse she's hiding in and set it on fire, make sure she burns, and burn her body again just to be sure.

"Something else changed, she hasn't gone after anyone else," Jack told them.

Outside the couple, Vena hadn't killed anyone else after attacking Ripley.

"What does that mean?" Lee asked.

Matt frowned as he suggested, "She doesn't want anyone else."

Remembering what Ewen told them earlier, he chewed on his bottom lip as Matt wearily looked around.

Jack asked what's wrong and Matt told him, "Rip's got a rare blood type, that'd be enough for her to take her mind off hunting other humans."

Helpless, Lee looked towards Jack as he chewed on his bottom lip before saying, "She can't get through those doors, there'd be no way for her to bypass the security."

If it's true, then that'd mean that Vena'll hunt Ripley by the smell of her blood and that'd mean she'd come back to the institution.

"She'll do anything to get in," Matt told Jack as he looked around. "Predators always have plans to getting in."

If Ripley taught him anything, if there's a will, there is a way, and Vena will find a way into Torchwood to hunt Ripley.

Going by vampire logic, Ripley has a rare blood type and to a vampire, that's like high grade caviar.

"Jack, what does that mean?" Lee helplessly asks as Jack stood up and reached into his drawer, bringing out his assigned firearm before shoving it into his holster.

"It means we're on lockdown and everyone together for an emergency meeting," Jack said in passing as he hurried out of his office to call everyone into formation.

Matt took the opportunity to hurry back to Ripley, she was asleep and he hated waking her up, but he had to warn her.

"Me?" Ripley blinked.

Matt nodded.

Pointing at her hand, he told her that because of her rare blood type, Vena's changed her patterns and now hunting her.

"How do you know she'll find me?" Ripley inquired the logic in that deduction.

There's no way Vena can find her. Ianto covered her wrist in time before her blood spilled on the docks.

By the time Ewen's done stitching her up, he had his jacket cleaned.

No chance for Vena to track her outside the blood on her claws.

Looking around, Matt frowned as he reminded her of what she told him.

"And if your wrong?" Ripley raised a brow at him.

Matt weakly smiled as he said, "Well, can't afford to be."

Helping her off the couch, Matt kept her close as he brought her to the circling members of Torchwood as Jack informed them of the possibility Vena attacking it to get to Ripley.

"We know she hadn't eaten in a while and suffered gunshot wounds," Jack began as he looked around. "She's going to be hungry and cranky, extremely irritated."

Gwen asked how they're supposed to kill her in Torchwood and Jack sighed as he chewed on his bottom lips before saying, "We'll trap her in the Prison Cube and set fire."

Hidden away for only specific situations, the Prison Cube. A cube that's big enough for the prisoner to be in and entrap them. No doors, no seams, nothing for them to use to escape. It's dangerous because of the power it generates to keep its integrity and Torchwood needed it for dangerous individuals, such as Vena, so they couldn't harm anyone else.

"How're we going to do that?" Stephen asked as he raised his bulky arm.

Jack's chocolate eyes moved towards Matt.

Instantly, Matt felt them on him and responded, "Did she know about it?"

Shaking his head, Jack said that Vena didn't, and Lee never told her. It's against the handbook. Only authorized personnel knew it existed and very few knew how to operate it.

Only Ianto and Jack knew how to operate the cube and they're hesitate in teaching others how to use it because of the power it holds and the delicate controls.

One wrong configuration and they risk killing themselves and destroying Torchwood completely.

It's because of this, they often avoid using the cube unless absolutely necessary.

"So, we get her inside and torch her, that's it?" Owen raised a brow. "You said nobody can breach Torchwood!"

Jack shirked in his spot before he stated that it's in theory.

Reasonably, those who want to get into Torchwood will do whatever it takes with whatever they have, but they have limits as anyone else.

Vena, her mutated state, she doesn't need to rest, she just needs to keep at it until there's some way for her to get inside.

"Ripley, this is going to sound completely crazy and I know it is. You have to go into that cube," Jack told Ripley that for their plan to work, she'd have to go inside that cube.

It's the only place Jack knew that Vena couldn't break through and a lot safer up here with them.

Jack stressed that Ianto won't let anything happen to her in that cube and that the control room is hidden away so even if Vena broke in, she can't find it.

Turning to Ianto, Jack instructed him to power up the cube and help Ripley inside, making sure she can get out but Vena can't.

Ianto said he can get the cube up and running in ten minutes. Might take longer since they haven't used it in a long time and the coils gotten cold.

"Make time," Jack said.

He turned his attention to Stephen.

"Stephen will go with you in case anything happens," Jack pointed at Stephen.

"Owen, Ewen, get some tranquilizers ready, make it high as you can go," Jack instructed the twins.

Nodding, they hurried to their office.

"Gwen, Lee, I need you two to sweep," Jack instructed them.

Torchwood lingo for them to track movements of known personnel and find any foreign movements.

"Right," Gwen nodded as she went with Lee.

Looking at Matt, Jack instructed him, "Doc, you come with me."

Matt looked towards Ripley and she nudged him her arm, telling him that she'll be fine.

"Keep her safe," Matt instructed Stephen and Ianto as he passed the men.

A sharp look on Matt's face as he said this before it disappeared and he followed Jack.

With their orders given, the team worked to prepare for Vena. There's some daylight left and they better use it, because come nightfall, she'll come back and she won't stop until she's in Torchwood.

While the idea of torching her outside the institution should've made sense, Jack didn't want to explain the damages caused by it unintentionally to his superiors.

They'll fry him on the spot for it, even if he had a good reason to do it.

"What if we're wrong and she doesn't come?" Matt brought up a good point.

They're assuming that she'll be after Ripley because of her rare blood type, but maybe there's parts of Vena still that knows that she can't get in the institution simply by getting through the door.

For all they know, she'll wait as long as she can before Ripley finally emerges from Torchwood and kills her. If not take her frustrations out on the very people Jack tried to save from her.

"She'll come," Jack looked around, holding up his service firearm. "There's nothing in her anymore, just an animal, a desperate one."

Emotionally distancing himself from her, Jack considered her a dangerous animal and that meant she won't stop at nothing to get Ripley.

Hiding her deep in the Torchwood won't dissuade Vena, she's just a creature with a dead woman's name and she's operating on her own rules.

"We'll find where she's at and lure her downstairs," Jack said.

Torchwood lingo for the bottom basement that nobody's allowed in unless absolutely necessary or instructed. It's got it's own locks and codes that nobody outside Ianto and Jack can access at a given time and nobody has the time to spend cracking code for the next trillion years.

"Okay, sounds easy enough," Matt shrugged.

Jack then brought up the real reason he contacted Matt.

"Oh, when we get her inside, I need you to do your thing and override the controls," Jack looked at him.

Matt asked what he meant and Jack explained that the controls are fickle and even if they wanted to destroy Vena, they can't.

"It's… hard… really… really hard… I've been captain here for… ten-fifteen years, I can't even get it to work half the time," Jack admitted that the controls for the cube aren't easy.

Even Ianto, master of crosswords, struggled.

It took Jack and Ianto, boxes of stout, just to figure out how to capture and release.

Killing's a different story.

"Why'd you have a cube you don't even know how to use?" Matt winced at Jack's admittance at his inability to use the cube.

Jack stated he'd only gotten the cube from his superiors after an unnamed incident where he needed it to capture a dangerous individual.

"Really evil guy," Jack told Matt. "Got the mind of a mad genius without the funny bits."

There was an individual that caused a stir, enough to get Torchwood involved.

Crafty, he subdued everyone he'd come into contact with.

The only way to stop him was to trap him in the cube that Jack had to beg for his superiors to give because the man was this close to killing them all.

Jack would've killed him outright, but the man wasn't going down easily and escaped the cube by frying wires and disappeared even before Jack pulled out his gun.

"One man?" Matt raised a brow.

Jack nodded.

"Yeah, creepy too. Not the, "Dateline" creepy, either. The kind of creepy where he looks at you and it's like he's reading your life story and not in a "oh isn't that sweet?" kind of way, either," Jack shuddered thinking about him.

Curious, Matt asked why he caused such a stir and Jack held a look on his face as he said to him, "Well, you were there, remember, you said the cube was a stupid idea, but hey, I got him in there, didn't I, yeah he escaped, but I caught him with it."
