Who's your favourite male NPC? (Patreon)

A few days ago we had a poll to see who your favourite female NPC was, and it's only fair that we have one about their male counterparts now.

The reasons behind your votes will probably be different in this case, but I'm interested to know: which character you find more interesting, considering his interactions with both Ian and Lena so far, story-potential and personality? Who do you want to see more of, get to know better, or have involved with the main characters moving forward? And who do you love to hate the most?
