Don't attack me for this BUT since John has become more popular (as has Dex), here are some spontaneous headcanons for their ship. Yeah. Them. I kept this inside for too long.
[sorry if there are any mistakes in text, English is not my first language.]
Because of John Dex start to drinking chamomile tea, cuz coffee made Poindexter too overexcited and twitchy which bothered Walker and he sullenly pushed the tea to the sniper. Especially if Dex had a stressful day before: "no, Dex, you'll try to sleep instead of work on documents with insomnia".
John is the more touch starved expressing this in a tight hug, a warm hand on the small of the back or a kiss on the cheek - he does such gestures all the time when he wants to show affection and tenderness. Dex is not quite like that, his manifestations are less obvious, but they are there - this is a hand on John's head (which is ruffling his already messy hair), stroking his knuckles after a hard mission or even the way Dex lazily leans against Walker, As that's how it's supposed to be.
Dex has a notebook in which he writes about people important to him and pastes random photos in there, too. Mercer, Julie, even Fisk - they all showed up there and Poindexter doesn't even remember how long he's been leading it. But John has been appearing in notes more and more often lately.
Walker often stares at the scar on Dex's back if Bullseye allows it. These moments are rare but meaningful. Even rarer Poindexter allows him to touch and Walker barely breathes with a thoughtful sound, tracing his back with his palm. They don't speak at such moments, but afterward Walker always kisses him on the forehead.
John calls him "pretty boy." In a joking manner. Or not - no one knows. Dex rolls his eyes every time (Walker might get hit in the back of the head with a walnut later. "A lucky shot," Poindexter assures him).
Dex likes the bump on John's nose often tracing it with his fingertips. Walker squints at these moments wondering how they got to this point.
They sleep in such a way that Dex lies on John's chest pressing him completely to the bed. In morning Poindexter complains about someone else's snoring (Walker denies everything).
Both have nightmares, but don't know how to talk about it and go for a smoke break. Often share one cigarette.
Many conflicts end in fights after both lie on the floor exhausted and breathing heavily. Sometimes they fall asleep just like that (will worry about broken furniture and shards of glass around tomorrow).
Walker may unconsciously stand behind people who are important to him, leaning forward and stretching his neck if he senses danger. Dex was not spared this. At first it made him laugh, then irritated him, but sniper come to terms with it and began to treat John like a guard dog at such moments. He still doesn't quite like this gesture from John, but tolerates - because it's Agent concern.
DexJohn incorrect quotes bcuz I'm slowly going insane with them.
My babies (John would have thrown him out of the window with broken legs the first chance he got; Dex would have thrown a toothpick into his eye socket).
I don't know what to write, but recently I was able to finish a sketch about DexJohn for the first time in a month, so if anyone wants to see it, the link will be here!! :)

Hope I'll be able to write more in the summer. I love them, but exams and the end of the year are killing me.
