There is, it's just flimsy and one-sided. From what I hear, the bonus storyline is Dylan falling over backwards doing everything he can to get under Ellie's skirt - fixing her laptop, covering for her smoking, kissing her at the coffee shop. Even stuff like Logan cheating on her is designed to soften her hatred of him with the subtlety of a meat tenderiser.
I'm just disappointed there's no story behind why Ellie hates him so much in the first place. That's what I was hoping the bonus storyline would be, and that would have been interesting. But sadly, pandering to the M/S crowd has won out at the expense of Ellie fans like myself and
farrah.
