Ace
A backpack full of nitro, a heart on fire, and zero patience for running away.
Ace, born Dorothy McShane, shattered the mold of the classic *Doctor Who* companion. Hailing from the council estates of Perivale in West London, she arrived not as a wide-eyed tourist but as a street-smart runaway armed with Nitro-9 and a chip on her shoulder. Her dynamic with the Seventh Doctor was a volatile alchemy: where he operated as a manipulative grandmaster pulling strings from the shadows, Ace served as his explosive blunt instrument, forcing him to confront the consequences of his schemes. Her journey is a raw psychological excavation; she evolved from a rebellious teenager running from her past into a self-actualized hero who realized that the only way to outrun her demons was to turn and face them.

Lore & Background
Ace's debut on Iceworld wasn't marked by wonder, but by survival. A runaway seeking escape from the suffocating ordinariness of Perivale, she was recruited by the Doctor who saw her latent potential beneath a veneer of aggression. Their partnership was often fractious; while the Doctor orchestrated complex, long-game manipulations, Ace frequently solved immediate crises with a stick of Nitro-9, acting as the chaotic counterweight to his calculated silence.
Yet, the true core of Ace's narrative is her brutal confrontation with the trauma she tried to bury. The Doctor deliberately steered them toward Perivale and encounters with the Cheetah People, forcing her to relive the loss of friends twisted by alien influence. This psychological dismantling was agonizing but essential, transforming a reactive teenager into a woman who understood that running only deepens the wound. Her departure from the TARDIS wasn't an abandonment of adventure, but a mature declaration: she had to return home to fix what was broken in her own life before she could truly save anyone else.
In Their Own Story
The Perivale alleyway screamed with wind, carrying the acrid sting of rain and stale exhaust. Ace tightened her grip on her rucksack, the familiar, dangerous weight of Nitro-9 sticks pressing against her spine. A few paces back, the Doctor stood silhouetted by a flickering streetlamp, his ancient eyes watching with that unnerving, knowing stillness.
"You don't have to do this, Ace," he murmured, his voice barely cutting through the distant traffic roar.
She didn't flinch. "I know I don't *have* to, Doctor. But I *want* to." She palmed the red plastic detonator, its warmth a stark contrast to the chill of the evening. "It's time I stopped running from ghosts and started fighting them." A grim, determined smile touched her lips as she stepped forward into the shadows, ready to burn away the past once and for all.
Reader's Guide
Ace McShane represents one of the most radical character evolutions in *Doctor Who* history. She began as a angry, disillusioned teenager with a chip on her shoulder and a penchant for arson, but through the Seventh Doctor's guidance (and trauma), she matured into a confident, self-reliant leader who could stand as an equal to the Time Lord himself.
