An Interdimensional Meet by fmfan1980 reviews
This story takes place after the Flash episode 'Flash back', and after Supergirl episode 'Manhunter'. This is my take on the cross-over. This story goes AU as far as Supergirl is concerned after 'Manhunter'. This is my first Supergirl/Flash X-over, and I hope it stays true to the characters. Please review.
