Lara knew Jayden in the past. She met him a long time ago...
When they meet again, Lara hopes that maybe at this present time, they can be more than just friends... Lara behaved in a way that implied she knew him, but Jayden didn't recognize her anymore. Instead, he thinks Lara behaves more intimately than is appropriate.
So Jayden throws some insulting words at Lara:
"Do I know you?"
When Lara heard it, she was hurt.
Would she stay? Or would she say goodbye?
Will Jayden be able to recognize her again?
Will he apologize to Lara if he realizes that they really knew each other before? Or will he just leave all their memories behind?
