Precognitive | 10th Doctor ¹

Cassandra Oracle is a scientist.

She calculates probabilities, maps out the differentials and keeps her findings to the fourth decimal point at least, in order to ensure accuracy.

But when she gets accidentally transported to a universe she thought fiction (thanks to the machine. she'd been working on), with a head-full of foreknowledge she shouldn't have about events to come. (thanks to her obsessions with a certain TV show), she realises that some things will never be explained neatly and precisely.

And mostly, that mad men in tie-travelling blue boxes really can make your dreams come true.
