CallaPix

(Add pic later)

CallaPix is a MES2 ship composed of Nathan Callaghan, Vito Shepard Pix and Solaryk Pix (the last two being married)

Reasoning
The Pixes are a very open couple, having shown interest, both physically and romantically, towards Nathan. While it's awkward as all heck at first, they grow closer, and literally all players (and Hark) got onto the CallaPix Bandwagon (I mean, it's the title of one of the episodes).

Lead Up
It all started in Session 2, when a slightly anxious and tipsy Vito mentions Nathan Callaghan being in the Top 3 of a threesome list Solaryk and he have. On top of that, Sol and Nathan have a real connection playing DDR. It's gotta count for something...

It grows even more awkward when a week/month (need to check) later (Session 3), the married couple invite Nathan over for dinner. "Many things need to go in the bedroom" Sol says. Had it not been for campaign events, maybe it would have been confirmed right there.

Things get even more awkward when the crew rescues Augustus Pix from Irune (Session 7 ish), as Auggie is: Vito grows increasingly worried for Nathan as stuff goes by, especially since biotics around them disappear out of thin air. In Session 15, Vito is kind of forced (in Nathan's lap) to let Nathan know what he thinks, truly, about him. The Pixes' door is always open, for casual stuff, as well as romantic stuff.
 * 1) Sol's brother
 * 2) Vito's brother-in-law
 * 3) Pixie August, a Fornax Porn Star Nathan used to really, really love.

Session 16 comes around, and the crew takes a break at the Pixes' home. After a busy night, it's hinted all 3 "sleep" in the same room...

Outcome
In session 16, the ship is heavily hinted to have become canon (at least physically). It's only in Session 19 that it's confirmed to be romantic as well.

Fun Facts

 * CallaPix is the first Triad Ship in Hark's campaigns!
 * The threesome list was only hypothetical, as Vito himself has a very low libido, being a Salarian.
 * Nathan is also the only living/existing person on that list. (He is third to Indiana Jones and Jeff Goldblum's ghost)
 * It was the one ship no one saw coming, mostly because Vito started the campaign unavailable.
 * It is also the only Ship Vito is a part of.
