   Summary

   Null Hypothesis (H₀)

   - A statistical hypothesis which asserts that no significance, relationship, or difference exists between specified populations or variables.

   Grace didn't know the bloody man he just pulled out from a submarine and Simon didn't know the blonde who took him out from it either.

   But why is it that they find familiarity in each other?

    

   Or:

   Two dudes find out they’re from alternate timelines through wonky research while being amnesiacs and an alien rock is just happy to help them.
