It all started when I started shipping Jimmy/Thomas because I apparently am not impervious to that sort of thing, though I'm not particularly invested or rabid about it I just like seeing them together. Then I asked from drawing prompts and Flippyspoon gave me one. And Rob James Collier joked about Thomas having a pet unicorn in an interview. And hot guys and nice clothes and unicorns and you know. It's fairly easy to push my buttons to draw.
And well... yeah!
