An hour later found Jemma pouring milk for her sisters who had just woken up. Fitz was standing watching the programmers who were working on the message to Rebecca. Agent Coulson walked back into the room.

"We have a perimeter around the station," he said, "and we have a team ready to go in and ambush these people-"

"A team?" Fitz was incredulous, "that's not going to work sir."

"I appreciate your help Fitz, but I've been doing this for a while and trust me," said Coulson, "I'm very good at my job."

"Fitz is right sir," Jemma piped up, "your plan won't work."

"Please, do enlighten me," Coulson had an edge of frustration to his voice.

"It's simple really," said Jemma, "you know that you have to take the twins into that station with you and I'm not letting them out of my sight."

"Since you didn't figure Jemma into your preparations, the plan won't work," finished Fitz.

"How did you know we needed the twins?" Coulson frowned, "we just figured that out ourselves." Fitz rolled his eyes.

"If you don't have the twins then there's nothing to keep the kidnappers from shooting the people you send in," he said as though it were the most obvious thing ever. Jemma nodded in agreement.

"What exactly are you suggesting Jemma?" asked Coulson.

"I'm going in there," she stated.

"We're going in there," corrected Fitz. Simmons sighed.

"We've been over this Fitz; someone has to stay with Lucy."

"It's not like there aren't hundreds of S.H.I.E.L.D. agents here to watch her Jemma."

"I want her with someone she knows, not some strange agent!"

"Whoa, whoa, whoa, slow down," interjected Coulson, "you think we're sending two completely unprepared students into a potentially dangerous situation?"

"No, you're only sending one," Simmons answered, still glaring at Fitz, "otherwise, I'm not letting the twins go." She finally faced Coulson, letting the ultimatum sink in. "Those are your choices, Agent Coulson."

"I can't send you alone Jemma," Coulson shook his head, "it's too dangerous."

"What if I went as well?" interjected Fitz before Jemma could respond. Coulson debated for a moment.

"I could probably swing that," he decided, "probably."

"No Fitz," Jemma shook her head firmly, "I won't let you-"

"Look Jemma, it's the only way for you to stay with them and get Becky back," Fitz stared her down, "we have to do it like this." Jemma pressed her lips into a defiant straight line, but she knew that Fitz was right. She looked at Agent Coulson.

"So what do we do?"

Fitz and Simmons crept quietly along the wall of the train station. They were both uncomfortable in the tactical gear they had to wear, but neither said anything. Angela and Sarah clung silently to the older kids' backs, dressed in dark clothing and shaking with fear. The station was abandoned and looked like it had been for quite some time, although S.H.I.E.L.D. had record of recent activity.

"Alright Fitzsimmons, you're clear to enter the building." Coulson spoke over the comms.

"Roger that," Fitz muttered back. Simmons and Fitz stepped through an open doorway and quickly slipped into the shadows off to the left. Jemma glanced down at her watch nervously. Five minutes, she thought. She flinched slightly when she heard Coulson's voice in her ear again.

"Simmons, we have a new message from your sister."

"What does it say?" asked Jemma, thinking it odd that Becky would send a message now.

"It just says...Seamus Finnigan." Coulson hesitated over the name,

"Oh wait...one more...this one says Run Neville." Jemma felt the blood drain from her face and her gaze dropped involuntarily to her watch.

"What is it Jemma?" Fitz was watching his partner worriedly.

"Simmons, what's this one supposed to mean?"

"She wants me to blow up the building," whispered Jemma.

"What?!" Fitz exclaimed, "we can't do that, we don't even have explosives, or-"

"We don't need them Fitz." Simmons unbuckled her watch and held it up.

"That's not..." Jemma nodded, mouth set in a grim line.

"We really need to have a talk about what your sister does with her free time," muttered Fitz under his breath.

"I don't know that blowing up the building is going to help us," interjected Coulson, ever the voice of reason.

"That's a fair point," said Fitz, "If Becky's in the building, won't blowing it up be a bit counter-productive?"

"It's….a bit complicated." Jemma sighed, "Rebecca loves to pretend to be a spy, secret agent, that sort of thing. Her favorite games to play were the ones where there was going to be a threat on all of our lives and it was up to her to save us. That's why we have a secret code, and that's where the watches came from."

"Watches, plural?" asked Fitz. Jemma nodded.

"We all have one. Even the twins. I'm the only one who wears it anymore, mostly to appease Becky, but also, I really needed a watch."

"You care to explain what the watches do, Simmons?"Coulson inserted himself smoothly back into their conversation.

"Each watch has two potential uses," explained Jemma, "either explosive or detonator. You use the buttons that set the time to prime the watch for whichever role it's going to play."

"How much of an explosion are we talking?"

"My watch alone is rigged with enough heptanitrocubane to bring down this entire building, plus some," Jemma hesitated, "Sir, there's something else."

"What is it?"

"You're going to have to let me blow up the building while Rebecca's inside."

"Are you mental, Jemma?!" Fitz stared at her as though she had gone mad, "We can't do that."

"Let me finish, Fitz," said Jemma, furnishing her partner with a glare, "Rebecca's been working on her watch longer then she worked on the ones she made for us…it has a few safety features."

"I don't suppose one of those features is going to help her survive a massive explosion, is it?" asked Coulson wryly.

"Actually…." Jemma trailed off for a moment, and then smiled at Fitz, "she has this shield that she designed and it's made out of Kevlar so it is pretty much fireproof…"

"How did she manage to get a full length shield to fold up into a watch?" Fitz was clearly wracking his brain, trying to understand the engineering behind Becky's watch.

"She did some kind of shrinking thing on it, I'm honestly not quite certain," Jemma shook her head, "she explained it all to me when she was doing it, but I didn't actually pay super close attention."

"That's very nice and all, but a shield isn't going to protect her from an explosion on all sides," said Coulson.

"This one will." Jemma grinned widely, "It wraps around her, creating a sort of bubble, leaving her enough air to breathe and a tiny bit of space to shift around in. It completely seals her off from the outside." There was silence on the other end of the comms as Coulson contemplated what she was saying.

"You can't actually be considering allowing this sir?" Fitz was incredulous, "We can't just blow up a building with a 14 year old girl in it, shield or not!"

"We can if she's the one telling us to do it Fitz!" argued Jemma, "Look, Rebecca is brilliantly smart; she's already figured out any possible way for us to rescue her and obviously, this is the best one. She knows, and you and I know too, that this is the only way to take out her captors and get her back without giving them the twins. This place will go up in flames-look how dry it is," she ran her hand over the crumbling wood, "and when the flames clear, we can pull her out." Jemma looked Fitz dead in the eyes, "Rebecca wants us to do this-no, scratch that, needs us to do this, Fitz, please." Fitz pursed his lips, uncertainty filling his expression. Their silent battle was broken by Coulson over the comms again.

"Do we need to reply to Rebecca?"

"Not for this one," answered Jemma softly, "She'll know as soon as my watch is primed." Fitz's face smoothed out as Jemma spoke and he nodded to her watch.

"Better get on that then, I know Becky doesn't like to be kept waiting."
