Valerie Frizzle pulls some levers and pushes some buttons on her dashboard, opening up a psychic link with the TARDIS core inside. Where will she take me next? she wonders.
The answer comes as raw concepts, too powerful for language, as usual pushing the edge of too much too fast for even a Time Lady's brain, but as always gentle enough to do no actual harm. Somewhere interesting. Somewhere with new phenomena to learn about and new people to meet.
So, same as always, then. Ms. Frizzle jokingly pats the console as the vortex opens, whirls around them for an infinite moment, and deposits them . . . somewhere.
"Well," she murmurs as she opens the door. "Time to take chances, make mistakes, and get messy."
