Yaz stood at the centre of a hurricane. Winds flicked at her clothes, and she fastened her jacket to stop it whipping at her sides. She was standing, but not actually on anything. There were galaxies above her and beneath her feet. The universe roared around her, and she fought her fear. Apparently this was what you got when you asked to see inside the Doctor's mind.

"Doctor?" she called, pleased with the steadiness of her voice, but was surprised to hear a different voice, maybe a teenage boy, say "He burns at the centre of time and he can see the turn of the universe."

She looked around for the source of the voice, but instead saw the lifespan of stars. "Doctor? Are you here?"

The boy again. "He's like ice, and fire, and rage. He burns at the centre of time..."

"Doctor?!"

"Yaz, I'm here," her friend's voice swept through her mind. "I'm trying to show you who I am."

In the stars above her head, Yasmin saw men moving. Confident white men of varying ages.

"These are who I've known I was before."

An old man with white hair, a clownish man, a man with white curls and a velvet coat, a wild-eyed man dangling a long scarf, a younger guy who was wearing what appeared to be celery, an angry man with curly blond hair, an older man with a strange umbrella, a younger, gentler one with brown curly hair, an older guy with a terrible flame in his eyes, one with big ears and a leather jacket, a young man with awesome hair, another young man in a raggedy jacket, and a last, a stern-faced man with white hair (Yaz half-remembered her Doctor saying "Half an hour ago, I was a white-haired Scotsman", and this image connects to that memory in her mind) and behind them all the sense of her Doctor, blonde, vulnerable, indomitable and unfathomable.

Yaz took a step back and collided with someone behind her. Slender hands steadied her, resting on her shoulders.

"Only me. Well, to be fair all of this is only me, but this is the part of me I've put here to be there for you. Okay?"

Yaz nodded and looked up at the men in the sky, most of whom seemed to be remonstrating with someone. The raggedy man was eating something. "Is that...fishfingers and custard?"

"Oh yeah, I'd forgotten about that! Honestly, a thousand years pass and you forget about your terrible lifestyle choices." Yaz's Doctor pulled a face at her past self. "He was what I thought of as my eleventh self."

"What changed?"

The stars dimmed and the Doctor showed flashes of the War Doctor meeting her past selves.

"Just this, at first. There was a massive war, and everybody lost. I was a soldier." The Doctor turned away from her memories. "There's so much blood on my hands, Yaz, and most of it I can't even remember."

Yaz slipped her hand into the Doctor's. "You did what you had to do."

"Did I?"

The Doctor waved her arm, and the Master appeared in the sky, along with several others that Yaz felt were probably his past incarnations. The Time Lord stared for a while, taking in each detail, then flicked a finger. The current Master spewed the news of the Timeless Child and the Doctor's forgotten lives, hatred and rage in every line of his face.

The Doctor snapped her fingers, looking away.

Now the sky filled with people, dozens, of all ages. Some talked to each other, some stood alone.

The Doctor looked at Yaz. "These are - were - ARE, my friends. I've been blessed with my friends over the centuries. They helped me in so many ways, and what good was I for them?"

A blonde in a union jack t-shirt grew in the sky, twirling in the hands of the big-eared leather jacket Doctor, as Captain Jack Harkness laughed to the side.

"Rose," the Doctor said softly. "I was new in that body when I met her. I wasn't that man for long. She and her family ended up in a parallel dimension with a weird hybrid kind-of-me."

The Doctor with good hair stood on a beach, wearing a pinstripe suit and a bittersweet smile. "I'm burning up a sun just to say goodbye."

Three others came to the foreground. "Amy, Rory, River."

"What happened to them?"

"Amy and Rory were pulled into the past by a weeping angel. I can't visit. River...Oh, I'll show you."

Again, flashes of a past life. Yaz's head spun, and the Doctor watched her with concern. "You okay? This is a lot of information in quite a small time. I don't wanna overload you."

Yaz managed a small smile, and intertwined her fingers with the Doctor's. "I asked for this. It is a lot, but like...I needed this."

The Doctor closed her eyes. The sky filled with a black hole, and the wind howled and whipped. Galaxies were drawn into the black hole, and the Doctor said "This is how I feel when I think of the past. There's just...so much loss, Yaz. If I think, it draws me in. When people ask questions, I feel it calling to me."

"So what do you do?"

The Doctor smiled awkwardly. "I make friends. I'm good at makin' friends, me. But sometimes my hearts get a little carried away."

And now, to Yaz's astonishment and embarassment, she is everywhere. In her police uniform on a train. Bewildered in the beauty of the Punjab and the Doctor's words, "Can't have a universe without Yaz!" Insisting to her mother that they're just mates, when inside both of them were starting to feel different. Waiting for the P'ting to eat a bomb. Taken prisoner along with Tesla. On the other side of divided time, stuck in 1901. Image after image flickering, and the black hole behind replaced with sunlight and sparkling galaxies.

"So, yeah. There's that." Yaz turned to the Doctor, and contact ended.
