Wally's Pov (no, he is not prostituting on vans)
" I'm from the future," she told me. I know that she wasn't lying because she had just crashed from the ceiling in a blue police box that is some how bigger on the inside. If I hadn't been ten at the time, I probably would have questioned why it was bigger on the inside, but at that moment, I would've believed anything she told me.
"How far in the future?", I asked
"Five years", she replied.
"What?"
"Oh no we didn't advance that much."
"Then how-?"
"This is from Galifrey, my dad's home planet."
"Wait your not-?"
"Human. I know, but I am from Earth."
"Then your half-human?"
"No, Wally. My grandparents were from the largest moon of Saturn, Titan."
"Okay…Wait, how'd you know my name?"
"You meet 11 year old me next year," she said as she got in the box.
"Wait! Who are you?" I asked
"Mercy," she said as the box, and her disappeared.
