Praise Or Pity, by
cidercupcakesJohn/Jo, het, R
The author has a light touch and yet manages to pack so much in such a short piece!
I Lost Two Cities, Lovely Ones, by
ishieJohn/Buffy, het, R
I can see how the 'verses could work. A couple of things in John's characterisation don't grab me, but it's my personal idea of John, you know; subjective and all that. A good, fun read.
What you're getting, by
hunters_retreatJohn/Eliot Spencer (Leverage), slash, R
A collection of prompt-written ficlets fitting together into a 'verse. I think it works, Eliot is a no-holds barred kind of character, isn't he?
Beasts and Outlaws, by
calamitycrowAU, Dean/OMC slash, plus Sam, John, and lots of original characters and canon well-knowns.
Many of you have probably seen this already (it's a very good, long SPN AU read). Although the story is not John-centred, John has a part in it and I liked it, it felt realistic enough to me (especially in regards to Dean/OMC) and John-enough, so much so that the author dedicated a meta-post to John's character in her story :) attention to details will get me each time, and, it's a really good story, worth reading.
The Visitor, by
ultraviolet9aGen. And one of my favourite John-comfort stories :D
