Summary
Dedicated to this commenter:
I enjoyed reading this fic. However, I am appalled by the lack of Cato Sicarius, Master of the Watch, Knight Champion of Macragge, Grand Duke of Talassar, and High Suzerain of Ultramar! Why isn’t he in this fic? Are you Ultraphobic perhaps?
(In other words, I got bored.)

Cato gets Laid (finally) by vyzz_undercover
Fandoms: Warhammer 40.000, Warhammer 40k (Novels) - Various Authors

Summary
Cato 'insufferable prick' Sicarius is terribly down bad for the XIIIth Legion's Ambassador. He hard copes—until he can't stand it anymore—and, finally, grows a backbone that's built for something other than warcrimes, warp related panic attacks, and being an conceited asshole his every waking moment.
Yes, he's getting the girl.
But he's also sure as shit still going to complain the whole time.
TL;DR: initial piss-poor cliche of "oh noooo ur freezing we need to spoon 𝓯𝓻𝓮𝓪𝓴𝔂 style" got out of hand and I went overboard.
(all is written from the big blue bastard himself's perspective)
