I've been just itching for C/E fic and all I've found has been gross and tacky and ridiculous. I love how you set in it in Dawn Treader, good call. And as much as I like some good smut, your choice to be delicate with the verbiage was perfect.

I'm so in love with this. If you have any notion of writing more C/E I will absolutely cheer you on!
