Derek Hale's first love has returned, but his wolf has already chosen Fiona.
🐺 TEEN WOLF SEASON 2 AU
THE HUMAN LUNA
🌙 STORY PREMISE
Season 2 begins much like canon. The terrifying Kanima is stalking Beacon Hills, hunters are becoming more active, and the tension between Scott McCall and Derek Hale is worse than ever.
But this time, there is another secret lurking beneath the surface...
A secret Derek has buried for months.
Fiona McCain.
Stiles's younger cousin.
Human.
Fragile.
Completely unaware that she is the one person capable of bringing Beacon Hills' most dangerous werewolf to his knees.
Not because Derek loves her.
Not because he wants her.
But because his wolf has already chosen.
His mate.
His Luna.
And Derek hates it.
Or at least that's what Fiona thinks.
🐺 DEREK HALE'S PROBLEM
Derek lost his first love, Paige Krasikeva, when she was bitten by Ennis and suffered horribly from the transformation.
Unable to watch her suffer, Derek ultimately killed her himself.
The guilt haunted him for years.
Or so everyone believed.
Paige survived.
She transformed.
And now, eight years later, she has returned.
Twenty-three years old.
Beautiful.
Sweet.
Gentle.
Everything Derek remembers.
Or so he thinks.
Derek is dating Paige again.
Part of him genuinely loves her.
She's his first love.
His first heartbreak.
The girl he never stopped mourning.
But something is wrong.
Because every time Fiona walks into a room...
His wolf becomes restless.
Protective.
Possessive.
Obsessed.
And it terrifies him.
🌹 PAIGE KRASIKEVA
On the surface:
Sweet
Kind
Soft-spoken
Gentle
Protective of Derek
Exactly like the shy girl Derek remembers.
But underneath...
Paige has become something darker.
Years of loneliness and pain twisted her.
And now she's terrified.
Because she knows something Derek doesn't.
Derek's wolf has chosen Fiona.
Not her.
Fiona.
A human.
Paige can smell it.
Feel it.
See it every time Derek instinctively positions himself between Fiona and danger.
Every time his eyes follow Fiona.
Every time he unconsciously protects her.
And jealousy is slowly consuming her.
🌼 FIONA MCCAIN
Age: 16
Species: Human
Stiles's younger cousin.
Everything supernatural seems drawn to her.
Fiona genuinely believes Derek dislikes her.
Whenever she speaks to him:
Derek is cold.
Short.
Dismissive.
Sometimes even rude.
Because being around her is torture.
The closer she gets...
The harder it becomes to control the wolf.
The wolf wants:
To protect her
To stay beside her
To mark her
To claim her
And Derek is terrified of what happens if he loses control.
So he pushes her away.
Again.
And again.
And again.
While Fiona silently wonders what she did wrong.
🐺 DEREK VS SCOTT (CANON)
Their rivalry is at its peak.
Scott believes Derek is reckless.
Derek believes Scott is naive.
Scott's View
Derek keeps turning people.
First Isaac.
Then Erica.
Then Boyd.
Scott thinks Derek is creating soldiers.
A pack built through fear.
Derek's View
Scott doesn't understand reality.
Hunters.
Kanimas.
Alphas.
Death.
People need strength to survive.
And Derek is determined to build a pack.
Even if Scott hates him for it.
🐺 ISAAC LAHEY — Derek turned Isaac because he suffered years of horrific physical and emotional abuse from his father, and becoming a werewolf gave him the strength and freedom to escape that life. 💛🐺
⚡ ERICA REYES — Derek turned Erica because she struggled with severe epilepsy, social isolation, and low self-esteem, and the bite cured her condition while giving her the confidence she had always wanted. 💅🐺✨
🖤 VERNON BOYD — Derek turned Boyd because he felt invisible, lonely, and trapped in a life where nobody seemed to notice or care about him, and becoming a werewolf offered him a chance to belong somewhere. 🐺🤝🖤
🌙 WHY DEREK TURNED THEM (CANON) — After losing his family and his Alpha status becoming increasingly threatened, Derek wanted to build a pack of his own, believing that giving people like Isaac, Erica, and Boyd a second chance through the bite would make them stronger and help them survive in a dangerous supernatural world. 🐺⚡🌙
🦎 THE KANIMA (CANON)
In Season 2 canon, Jackson Whitmore is bitten by Derek.
But because of Jackson's deep self-hatred and identity issues, he doesn't become a werewolf.
Instead...
He becomes a Kanima.
A reptilian shapeshifting creature.
A supernatural weapon.
The Kanima doesn't choose its own victims.
It obeys a master.
And in canon that master becomes...
📸 MATT DAEHLER
A lonely, bitter teenager.
Years earlier he nearly drowned during a swim team party.
The people responsible never faced consequences.
Matt wants revenge.
Using the Kanima.
Using Jackson.
Using murder.
📸 MATT'S OBSESSION WITH FIONA
Then Matt notices Fiona.
And everything changes.
At first it's curiosity.
Then fascination.
Then obsession.
Then something far darker.
Matt becomes convinced Fiona belongs with him.
Not Derek.
Not Scott.
Not anyone else.
Him.
He starts watching her.
Learning her schedule.
Following her from a distance.
Collecting photos.
Making excuses to be near her.
And every day the obsession grows.
Because unlike everyone else...
Fiona is kind to him.
And Matt mistakes kindness for affection.
🦎 THE KANIMA'S NEW ORDERS
Soon Matt's priorities begin shifting.
Revenge isn't enough anymore.
Now he wants Fiona.
Protected.
Possessed.
Kept.
Anyone who threatens her becomes a target.
Anyone who gets too close becomes a target.
And when the Kanima starts attacking people connected to Fiona...
The pack realizes something is horribly wrong.
🐺 DEREK'S WORST FEAR
The moment Derek discovers Matt's obsession...
Something inside him snaps.
Not because Matt is dangerous.
Not because Matt controls the Kanima.
But because Matt wants Fiona.
The wolf immediately identifies him as a threat.
And for the first time in months...
Derek struggles to maintain control.
Because every instinct screams:
Protect.
Claim.
Destroy the threat.
And Paige notices.
Every second of it.
Every glance.
Every growl.
Every protective reaction.
Every moment Derek chooses Fiona.
Even unconsciously.
And the realization slowly breaks her heart.
Because after waiting eight years...
After surviving for him...
After coming back to him...
Derek's wolf has already chosen someone else.
A human girl who doesn't even know she's being fought over.
