Desperation.
That day Amy came home all pale crying, pacing around, and not replying to any retorts send her way. Melody felt some sort of relief and satisfaction in seeing her so broken, so sad. It was beautiful to watch really. She knew to get so angry with her watching her cheerful, blessed with her life with the Doctor. Running around on an adventure while Melody waited for her turn. Now when she saw her cry it was almost catharsis. She was so close in fulfilling her destiny that she could smell the fear, tears and death. It was so personal she wanted to feel it happen, she wanted to look into his eyes and see the end.
But before that she had to be sure this was the moment. She had to make Amy talk. She was always ready to speak of Doctor when they were young but now days she had to squeeze information from her.
"It's like you fear I would steal a Tardis or something" Melody said.
"I know you would steal a Tardis if given chance" Amy retorted absently.
"What happened this time?" Melody had to ask directly.
Amy just shook her head and cried.
"He should have call already" Rory said angrily and jumped out of his chair where he just watched Amy pace around, now he looked like a man that would wear Roman clothes and burn a fleet of ships.
"No, no, no" Amy repeated "he'll call when he's ready… will he. She is lost out there… how could we just leave…" she grabbed Rory's shirt and Melody felt glee seeing her mother taking her blame. It was proper that she feels guilty, although Melody didn't know what guilt feels like, she knew how it looks.
"She wasn't there at all" Rory tried to soothe her and Melody wanted to punch him, this feeling must last, not just dusted away like it never happened. "You held a flesh baby, who knows where she really was, they took her away."
"But when will I hold her, real her" Amy cried out now really crying holding tight to Rory's shirt and Melody could see he was crying too.
"Soon" he said despite despair that could be seen on his face "they can't hide her from him, not for long."
"But I must see her now" Amy got angry "we'll summon him."
"Summon him?" Rory was confused. "He surely won't come roaming around here just for kicks, he has a job to do."
"But he had all the time and space to do it. And he's looking in all the wrong places" Amy was now gaining control. "Probably tracing signs around us that has no meaning."
"So how will you summon him, he doesn't answer his phone" Rory was desperate glancing at Melody they forgot in the corner.
"You can always draw his name in a field, like giant sign" said Melody. "I bet he reads papers while he looks for that someone."
They both looked at her baffled.
"But how will we make it big enough to be noticed?" Amy started to think practical.
"With a car" said Melody.
"But how will we spell it right" Rory frowned turning imaginary wheel. "We can't see it from air, can we while we're driving."
"I'll draw it to you, with turnings" Melody took a piece of paper. "I wrote with cars often enough to know."
"When did you…" started Rory but was cut off by Amy.
"Never mind when" she said. "Mels you're a savior" mother hugged her tightly. "I'll tell you one day how big savior. Now draw, we don't have time to lose, I'm getting older here by a minute."
Melody drew a map for them and for a moment, while both of them hung by her shoulders looking at what she's writing, she regretted that they won't find her young enough to be useful. She knew that for sure because she walked her life and they weren't there.
After they left all she had to do is prepare herself for the meeting of a life time. She did that by dressing up and stealing a car. Nothing is better for lifting adrenaline and making yourself sharper than a good chase. She was excellent at them.
