Rec the Thing

diegetic_exchange is for in-universe fanfic/RPF/etc. Here are some things I enjoyed from it!

Babylon 5

Stars Uncrossed: My Vorlon Sex Story! (1300 words, explicit)
OF COURSE there is Vorlon/human reader insert smut on Future Space AO3, and of course there are some very recognizable Space AO3 usernames in the comments. The author's notes are also pure gold. MINBARI DNI.

Megamind

Am I the Asshole for impersonating someone else to be with my girlfriend? (700 words, Megamind/Roxanne)
The most in-character thing ever. The comments are great, and also extremely in character.

Murderbot Diaries

Bot Sacrifice (600 wds, gen)
Sanctuary Moon fanfic with ART's inline beta comments. Hilarious and very them, and also very touching.
