It had been a miracle that Severus Snape survived the Second Wizarding War. In fact, Harry, Hermione, and Ron could have sworn they saw him die in the Shrieking Shack. Instead, as they later realized, they saw him lose consciousness. It was shocking, to say the least, when Bill Weasley, who'd been sent to retrieve the body, came back with a faintly breathing but very much alive potion master.

That had been seven months ago, and the former headmaster had laid in St. Mungo's ever since. The Healers had just barely managed to stabilize him and placed him in a potion-induced coma while he healed. When no family stepped forward, Harry Potter himself took responsibility for the other man. Before long, Harry got wrapped into hunting down the Death Eaters that had evaded capture. He ended up warding the older man's room to prevent any of the uncaptured Death Eaters from harming the man that had betrayed their master. He made it a point to visit the man at least once a week, during which he would tell him about what was happening in the Wizarding World. He told him of all the new captures, the reconstruction of Hogwarts, hell, he'd even read aloud from a potions magazine. His topics of conversation rarely ventured to his life. He figured that if the man could hear him, he definitely wouldn't care about Harry's personal life, so he stuck to small talk and the like.

It had been three weeks since the woman claiming to be Snape's daughter had visited. Following that, his condition seemed to have improved a bit. The Healers still weren't sure when he would wake, but his breathing had grown stronger and he had twitched a few times. She hadn't returned since then, and Harry wondered when she would. In the meantime, Harry had scoured every resource he had for some mention of Snape's daughter. He'd looked through Hogwarts enrollment. He'd asked Dumbledore's portrait, but the old man had waved him off without ever actually answering the question. He'd even asked Order members, but they hadn't helped him much. No one had seen Snape with a woman, definitely not long enough for him to have fathered a child. But then again, no one had really cared either.

Harry was sitting at Snape's bedside on the first Thursday of December, telling the man about how the greenhouses at Hogwarts were finally back to normal, when the woman appeared in the doorway. Harry stopped mid-sentence.

A smirk played on the woman's lips. "Hello," she said after a moment. Her voice was much warmer than last time, and she had swapped the heavy cloak for a simple black robe, which she had left open, revealing casual Muggle attire.

Harry's mind raced with questions for her. Why did she and Snape bear no resemblance? When was she born? She looked a few years older than him, so how was she born when Snape was still at Hogwarts? Who was her mother? Who was she? And where had she been? Why did she wait six months before visiting her father?

The woman stepped into the room and stood at the other side of the bed. "You want to know who I am, don't you?" She sounded amused. Harry could only nod, and her smirk took full form. "Calypso Snape." She held her hand out over the bed.

Harry gave her a small smile. "Harry Potter," he said, shaking her hand.

When they separated, Calypso turned to her father and put a hand on her hip. Her robe shifted and Harry took careful note of the wand tucked into the waistband of her jeans. She blinked at him and smirked again as she realized what he was looking at. "No need to worry, Mr. Potter. I do not wish to harm anyone in this room." She turned her attention back to Snape, reaching out and moving a bit of hair away from his face. "He looks much better."

Harry stiffened as she touched his charge. Even if she was really Snape's daughter, he didn't quite trust her. "Yes, he does," he agreed.

The woman laughed, a small, tinkling sound. "Mr. Potter, you really needn't be so tense. I assure you I do not wish to harm you. I have to thank you for caring for my father while I was unable to." She looked down at the man in the bed. "But now, really, Father. I think you've had quite enough time to recuperate."

The man twitched and groaned. He lay still for a few moments before his breathing shifted. His mouth opened before he spoke in a deep, gravelly voice. "Oh, have I?"

The woman smiled, her eyes lighting up, and Harry could have sworn her golden hair glowed. "Father!"

"Calypso," he said softly. His daughter beamed at him.

Calypso looked at the other man in the room, whose jaw had dropped. "Mr. Potter, could you please fetch a Healer and tell them the good news?" She asked sweetly.

"O-of course," Harry said, standing and nearly stumbling in his eagerness to alert a Healer.

Father and daughter watched him leave. "What is Potter doing here?"

Calypso looked down at the man. "It seems you've been in his care, Father."

"Bloody hell."

By the end of the week, Snape was given a clean bill of health, and the St. Mungo's was glad to see him go. They'd much preferred him unconscious as opposed to the snarky and cold man that had taught half of them. After waking, he had all but kicked Harry out of the room with no more than a curt thank you dragged out of him by Calypso. However, that hadn't deterred Harry. He'd come back a few times after that, wanting to know how his former charge was recovering. Calypso rarely left her father's side, and she and Harry had conversed every time he visited, though their chats never went beyond tense small talk. Harry wanted to ask her his questions, but between Snape and the general uneasiness he felt around Calypso stopped him. He still wasn't sure he believed she was his offspring, but as Snape seemed normal and comfortable around her, he didn't push.

Eight days after he'd woken, Snape was released into Calypso's care. Harry had seen them off, and the woman had given him a brilliant smile as the two disapperated.

Father and daughter reappeared on the edge of a thick wood. Before was a clearing where sat a small cabin. "He placed a tracking spell on you," Snape said as the two walked through the light snow to the porch.

"He tried to," Calypso corrected, opening the front door.

"Very good." Snape stepped into the house, looking around the cozy sitting room. "So, this is where you've been hiding all these months?" Snape raised an eyebrow at her. Calypso only nodded before gesturing for him to sit and disappearing into the kitchen. She returned after a few moments and placed a cup of tea in front of him.

"I purchased it two years ago. It has all the standard wards, but I've also made it Unplottable. I prepared a room for you earlier this week, and once you're feeling better, I'll show you my lab." Calypso sat in the armchair beside him. The two talked for a while longer before she showed him around the rest of the cabin.

At the end of the tour, Snape stood in the sitting room, looking at her various knick knacks. "Calypso?"

"Yes, Father."

"It suits you," he said after a while.
