When Kara Zor-El crashed to the Earth, she had a difficult time adjusting to her new life. Riddled with amnesia, she tries to forget all about her past and create a new life with the help of her cousin, Superman. Spending time with Clark, also meant she spent a lot of time with Batman. And how the time was spent...;)

It's been ten years since Supergirl and Batman met for the first time when her pod landed in Gotham Harbor. They still dislike each other as much as the day they met but when an opportunity arises that causes them to spend more time around each other out of the alter-ego tights, do they really hate each other as much as they thought?
