In a heartbeat, Granit Xhaka and Matteo Guendouzi converged on Theodore from both sides, looking to snap the ball off the teenager's toes.
But Theodore didn't panic.
He waited for that exact split-second when both Arsenal enforcers fully committed their weight to the tackle.
Just as they lunged in for the kill, he slipped a delicate, disguised pass straight through the closing gap.
The ball rolled perfectly into the path of John McGinn.
The gritty Scotsman had ghosted up to the edge of the Arsenal penalty arc. Because Guendouzi and Xhaka had sold out entirely to stop Theodore, they had left the midfield completely vacant.
McGinn found himself totally unmarked in a lethal zone, and everyone in the stadium knew he packed an absolute rocket in his left boot.
"McGinn in acres of space!" Peter Drury's voice boomed over the broadcast. "He pulls the trigger!"
McGinn laced it, sending a heavy, swerving strike toward the net!
But David Luiz read the danger brilliantly.
The veteran Brazilian center-back threw his body across the line of fire, taking the shot flush in the chest with a sickening thud. The block killed the ball's momentum dead.
"Crucial intervention from David Luiz!" Gary Neville praised instantly. "He puts everything on the line to deny a certain goal!"
The blocked shot ricocheted back out into the midfield, and Xhaka reacted fastest to mop up the loose ball.
Instantly, the Emirates roared to life. The Arsenal counter-attack was on.
The Gunners surged forward in a terrifying, three-pronged assault.
Bukayo Saka tore down the right flank, Nicolas Pépé flew down the left, and Pierre-Emerick Aubameyang sprinted straight down the throat of the pitch.
All three attackers were making blistering, defense-splitting runs.
If Xhaka picked out any of them, Villa would be completely ripped apart. Xhaka got his head up, scanning for his captain.
But before the Swiss international could even draw his leg back to ping the pass, Theodore arrived.
Having seen McGinn's shot blocked, Theodore had sprinted back to cover with everything he had.
He launched himself into a ferocious, perfectly timed slide tackle, hooking the ball away a fraction of a second before Xhaka could release the pass.
"Theodore Bjorn!" Drury shouted, the pure adrenaline evident in his voice. "What a magnificent sliding challenge! He completely snuffs out the Arsenal break before it even begins!"
"That is world-class defensive awareness," Neville chimed in. "If Xhaka makes that pass, Villa are absolutely dead to rights. Bjorn bails them out massively."
Down in the technical area, Dean Smith wiped a cold sweat from his forehead. He rushed to the very edge of his box, frantically making downward pressing motions with both hands.
"Calm down! Keep your shape!" Smith screamed at his players. "Focus on the block! Do not open up against them!"
The clock ticked past the thirty-fifth minute.
With only ten minutes left until the break, Smith knew that conceding a third goal now would effectively kill the game.
For that final, grueling stretch of the first half, the Villa squad stuck to Smith's desperate instructions to the letter.
They abandoned any pretense of attacking, retreating entirely into their own half. Even Wesley dropped deep to bolster the numbers in midfield.
Smelling blood, Arsenal poured forward in relentless waves.
Saka and Pépé unleashed their full offensive arsenals, repeatedly terrorizing the flanks with their sheer pace and trickery to pry the defense apart.
The Villa backline was pulled left and right, looking incredibly fragile and disorganized under the heat.
But while Arsenal's buildup play was dazzling, Villa's sheer numerical superiority inside their own penalty area made it a nightmare for the Gunners to carve out clear shooting lanes.
The referee finally blew his whistle, bringing the first half to a close at 2-1.
...
Arsenal walked down the tunnel with a deserved lead, courtesy of Aubameyang's lethal poaching.
Inside the away dressing room, Dean Smith's halftime message was blunt: Defend for your lives.
He was convinced that trying to go toe-to-toe in an open game with Arsenal at the Emirates was tactical suicide.
Meanwhile, the global media reaction to the first forty-five minutes was absolutely scathing.
Sky Sports: "Arsenal assert their dominance at the Emirates! Emery's wingers have battered the Villa defense. The promoted side's miraculous winning streak looks certain to end tonight."
The Athletic: "A one-sided affair in North London. Aston Villa are being suffocated. Theodore Bjorn is trying to pull the strings, but his team looks miles off the pace against a resolute Arsenal."
The Guardian: "Villa's worst half of football this season. They look terrified of the occasion. The only player wearing claret and blue who deserves any credit is the seventeen-year-old Bjorn, who single-handedly stopped it from being 3-1."
On Twitter, the sentiment from the fanbase was equally grim.
@HolteEnder99: Honestly, I wish I hadn't stayed up for this. We look hideous. Eighty percent possession for Arsenal. We're just clinging on.
@GunnersHub: A complete mismatch. We are absolutely toying with them.
@EPL_Scout: It's a guaranteed loss. Villa can't even string three passes together to build an attack right now.
@RedDevil82: Theo is working his absolute socks off, but football is a team game. One kid can't carry an entire squad against this Arsenal side.
@VillaTillIDie: Stop writing us off! We are only down by one goal. If anyone can pull a bit of magic out of thin air, it's Theo!
...
Fifteen minutes later, the two sides emerged for the second half.
Villa kicked off.
Wesley rolled the ball back to Nakamba, who tapped it across to McGinn.
Five seconds into the half, the ball found its way to Theodore.
Matteo Guendouzi immediately stepped up to press him.
Instead of looking for a safe, sideways pass, Theodore dropped his shoulder, utilized a vicious change of pace, and blew straight past the Frenchman.
The sudden, aggressive dribble caught the entire Arsenal midfield completely off guard.
Having spent the first half trying to cut off Theodore's passing lanes, they hadn't expected him to put his head down and drive directly through the center of the pitch.
Panic set in.
Xhaka and Dani Ceballos abandoned their defensive shape and sprinted toward the teenager, desperate to close him down.
It was the exact reaction Theodore wanted.
Just as the two midfielders converged, he slipped a deft, outside-of-the-boot pass out to the left wing.
He found Jack Grealish.
Because Xhaka and Ceballos had been sucked inside to stop Theodore's surging run, Grealish found himself completely isolated against Sead Kolašinac.
"Grealish is one-on-one!" Drury roared as the Emirates held its collective breath. "What will the Villa captain do here?"
Up in the stands, the Arsenal fans fell dead silent, every eye fixed nervously on the Villa number 10.
Grealish didn't hesitate.
He drove hard at Kolašinac, threw a rapid step-over, and violently chopped the ball inside onto his favored right foot.
"He cuts inside!" Neville shouted.
Grealish, possessing elite footballing intelligence, knew this was the moment.
By shaking off the bulky Bosnian full-back, he had opened up a crystal-clear shooting lane right on the edge of the penalty area!
