The pairing of Caspian and Susan got its origins from Narnia movie-verse in which Prince Caspian and Susan steal glances and flirtatious banter, ending in a farewell kiss. Though Susan kisses him, she says it would have never worked out because she is 'after all, 13,000 years older than [him].'

Lovingly dubbed 'Casue' by Caspian/Susan shippers, Caspian and Susan's relationship is also present in AU (alternate universe) fanfiction, manips, art and fanvids which can be viewed on this site.

In interviews with Ben, Anna, and the director of the 2008 film, which were originally posted on MTV.com, the controversy over the romance was addressed: "[The romance] sat very uneasily with Anna [Popplewell, who plays Susan Penvensie,] and I as well, 'cause we had both read the book, and obviously it's not in the book," star Ben Barnes admitted. "We thought, 'You can't just stamp this on top of it. It's ridiculous.' "

Ridiculous at face value, maybe, but actually quite natural and subtle, director and co-screenwriter Andrew Adamson insisted, defending his choice to include the subplot.

"Our kids are growing up. Susan is 17, 18 years old — Caspian's a very fine-looking young man. Why wouldn't there be some romance? Just look at the two of them," he asserted. "It seemed more unnatural not to have the attraction than to have it. I don't think it's over the top."

"I think fans are worried that they're going to see some teen romance," Popplewell echoed, championing the subplot's delicacy.

 "There's no love scene in this film. It's very much a question of looks here and there."

"They're in their adolescence," Barnes added. "People shouldn't be embarrassed or upset about it because it's not on Page 79 of the book."

And at the end of the day, isn't it up to the fans of Narnia (in both the books and movies) to enjoy the world C. S. Lewis created in all its facets? So if you haven't already, why not give a rare, somewhat scorned ship a try? There are many het ships out there that require just a few plotbunnies to stay afloat.
