Fracture is the episode n° 12 of the 7th season.
A man obsessed with Kara shot Lex, who has found her, and he’s found in a comatose state.
Clark needed to find Kara and he decided to dive into Lex’s mind to discover where she was.
In this way Clark found little Alexander and evil Lex…. And more he saw many Lex’s memories…
So it was basically a journey inside Lex’s mind.
A gifs recap:



Now I was wondering what if (for another reason) it was Lionel the one injured instead of Lex? And what if Lionel has a secret to be discovered and, instead of Clark, it was Martha the one who wanted to dive into his mind?
She would surely find a dark side of him…but then she would find another side of him, the side of him which has feeling for her! So it would be a journey inside Lionel’s mind among dark secrets, hotness and sweetness and love…
