"Grandma, come on, we need to get going" Virgil called from the piano.

"Alright dear, I'm just checking I have everything" Grandma said calmly looking through her bag.

"How many times has she checked now?" Gordon laughed leaning against the piano.

Virgil shook his head "about five times in the last two minutes."

"Alright Virgil, I'm ready."

Virgil stood up from the stool "let's go. See you in Thunderbird 2 Grandma."

Soon Thunderbird 2 was leaving base and she took to the skies.

"Lights are all green, on route to London."

"FAB, have a good trip."

"Thanks Gordon."

Back in the lounge Scott joined Gordon who was typing up a prank.

"So, Virgil's gone then?"

"Hey. Yeah, they left about five minutes ago. Grandma was pretty persistent that she took her map and compass."

"But Virgil's wrist communicator has both of those functions" Scott laughed.

"I know, but Grandma doesn't trust our gadgets for some reason" Gordon smirked "well, I'm going for a swim, so don't think about test flying."

"Would I do that Gordon?" Scott winked "I'll go and see if Kayo needs any help with Thunderbird S, Virgil should be arriving in London soon."

The two boys left the lounge not knowing their family was about to fly into danger.

"Just because Brains has designed something new for your wrist, doesn't mean it's necessarily trust worthy" Grandma crossed her arms "maps have never let me down."

Virgil sighed "sometimes new things are better Grandma, you have to have more faith in technology."

Suddenly an alarm went off and the lights in the cockpit went out.

"You were saying about technology?" Grandma said sarcastically earning a slight frown from her grandson.

"This isn't normal, we haven't got any power" Virgil said with a frown "and it's not just Thunderbird 2. Look?"

Grandma looked out at London below them "I don't see anything wrong."

"It's too dark, it must be a power cut" Thunderbird 2 began to plummet and Virgil panicked "we're going down fast, we need to land now!"

John decided to check on Virgil's progress on the map but something made him look twice, why wasn't London appearing on the map?

"Thunderbird 5 to base, anyone there? Looks like no, let's try the hangers."

"John, what's wrong?" Scott asked as his brother's hologram appeared on his watch.

"It's London Scott. It's disappeared."

"What!? Look, I'll get the others and group in the lounge, give me five minutes."

"FAB" John bit his lip, what had happened to his brother?

Eventually everyone was gathered in the lounge and John continued his message.

"London isn't registering on the map."

"What do you mean?" Scott frowned.

"There are no lights on any buildings. Nothing, there's absolutely nothing."

"Can you get through to Virgil?" Gordon asked.

John shook his head "no, I can't. Thunderbird 2 isn't showing up either."

Scott paled ever so slightly "I wonder what's happened to them?"

Kayo smiled sympathetically "it's alright Scott, Virgil is fine I'm sure. He can handle himself in an emergency."

"But what if he's crashed?"

"John, if you get any word, or hear anything from London, let us know right away" Gordon said sternly and John nodded.

"You've got it. I would do a search of London for news, but that wouldn't appear on any frequencies."

Meanwhile Thunderbird 2 had crash landed in Trafalgar Square and Virgil was inspecting the damage.

"Looks like London is down" Grandma looked around at the buildings "there's not a sign of anything."

"It's gotta be some sustained EMF, an electronic magnetic frequency powerful enough to knock out all the electricity in the city."

"You've got the last bit right that's for sure. Look up there" Grandma pointed to a buckling crane where a girl was shouting for help.

"How am I supposed to get up there without any gear? This is hopeless" Virgil closed his eyes in frustration then felt a warm hand on his shoulder.

"It's not the gear in there that rescues people, it's the Tracy, now climb" Grandma pushed Virgil forward and watched him climb up to the crane's operator, and it wasn't long before the crane's load fell away and Virgil lowered himself down, however, he didn't look happy.

Virgil walked sorrowfully towards his grandma "she's still trapped, I may have lifted the weight off that crane but the door is still jammed. People in 2060 aren't equipped for life without electricity! I can't do anything without help and I can't get through to my brothers" Virgil hit the side of Thunderbird 2.

Grandma crossed her arms "now that's not true, you don't need help, all you need is trust in yourself."

"But I've always had access to my brothers" Virgil's eyes watered slightly "I've never had to tackle anything like this on my own" a tear fell down his cheek and he quickly wiped it away "that girl is trapped and I've done nothing but the littlest effort to try and save her."

"Virgil" Grandma said softly "you have more skills than you know, I don't know much about your rescue business but what I do know is that it's not always about what equipment you have."

Virgil smiled tearfully "thanks Grandma. I guess usually Thunderbird 1 is here and I have Scott to guide me. What would he do?"

Grandma frowned "surely we need to figure out what's turned the power off. If I know Scott, he would try that."

"Alright, where do we start?"

At the same time John and Brains were asking the same question.

"So Brains, any ideas what's happened to London?" John turned to the scientist.

"I can only think it must be an electricity disrupter, something called an EMF."

"An EMF? Well that would explain why motors would go down" Scott interrupted "if it's brought down Thunderbird 2, I can only hope Virgil landed before the power cut. I dread to think of the outcome if he was approaching London."

"Don't think like that Scott."

"But what if he has, he could be seriously injured and we can't even find out. If you hear anything John, call me as soon as possible."

John smiled sorrowfully "sure. Now relax, I have my full focus on London."

Back in London Virgil and Grandma were still planning their next move.

"Grandma, how are we going to find the centre of London without my GPS working?" Virgil looked down at his wrist communicator.

"With these" Grandma held out the compass and a map which Virgil grabbed "this is strange, look, the compass isn't pointing north, it can't be that omg can it?" Grandma shook the compass.

Virgil rolled his eyes slightly "EMF, but wait. That stands for electro-magnetic frequency, magnets affect compasses. This could help us to find the device."

"Lead on Virgil."

They left the cranes and Thunderbird 2 behind and walked off in the direction of Piccadilly Circus following the compass, they went down a narrow road going past the station.

Author's note: to be continued...very soon :) I know it's silly but I had to make Virgil cry, he seriously looked like he was going to in the episode. I'm so loving the new Virgil, very handsome and amazing.
