This is the story of Jem and Tessa finding their way back to each other after what happened after the bridge. Eh. Really more of a Jem and Tessa making loving to each other for the first time scene. 
 (view spoiler)[Ah! Jace is related to Will and Tessa! Makes me want to re-start the mortal instrument series that I gave up on. (hide spoiler)] 
 Does contain Mortal Instrument series spoilers.
