Scintillae Rosae (Pink Sparks)

'To understand what we're about to telll you, you need to do something first.' I smile at Barry.
'You need to believe in the impossible. Can you do that? Great!'
'My name is Barry Allen.'
'And I'm Anna Johnson. And we're the most powerful people alive.'
'Our story is pretty simple: our whole life we've been running. Usually from bullies. Sometimes we escaped, sometimes we did not.' I take it over and say:
'But after the most terrible nights of our lives, we were running from something a lot scarier. Something we could never explain. Something impossible.'

In a flash, the lives of Barry Allen and Anna Johnson are changed. The childhood friends have spent their whole lives chasing the impossible, never imagining that they would become the impossible.
