Good grief. This thread certainly took on a life of its own after my whingy OP.
I'd first like to state that I am waiting patiently for Aristocra Saganu to magically not be dead and take my Agent away to pick up where we left off on Hoth.
To those that asked, yes I carried the romance through to the finale, and married him despite my misgivings because I wanted to see the ending. No, I am still not going to join the ranks of the Bug-boy fan club, and here are my observations:
1) Vector is an alright kind of dude. He's had a tough time of it (particularly when Lokin's dialogues are explored) but you know, things could be a lot worse. I thought it was pretty neat that Vector and Lokin are actually friends outside of the spaceship. That said, Vector is still not remotely romantically attractive. Sorry dude, but your weird bug issues and difficulty with understanding and comprehending the emotions of other people place you firmly in the buddy box, no hugs for you unless they're sidehugs in a platonic manner.
2) Following that point, the Agent's flirt options are still horribly contrived, especially at the beginning of the romance. He will be talking about something, anything - usually bugs - and the Agent reacts like it's simultaneously the most fascinating and arousing thing she's ever heard. "I hear the song of the universe" ->Vector lets rub forearms! "I want the Killiks to expand and get in touch with other hi...-" LETS RUB FOREARMS. "I'm planning universe wide Killik domi..-" -> VECTOR. FOREARMS. I'LL BE WAITING IN THE BEDROOM. There is nothing even faintly attractive there, nor any natural opening for flirtation, but the Agent throws herself at him with a passion that defies credibility, and he doesn't even realise for ages because he's too busy contemplating his chitinous navel.
3) That Scene. Yes I got to that scene and I did the deed. Having done two more romances since (Torian and Quinn), it's actually probably the best scene out of the three of them. He's creepy as, but it was quite nice that he tried very hard to hide the creepiness. However, his snap back to Killikhood immediately afterwards was unnerving, especially given I put a mod on him (for That Scene he shows up as his default face but once he goes Killik again he snaps back to the custom mod).
4) The marriage dialogue. Now, from reading some of your empassioned posts I can see that there's some way of making him realise that being Killiky is really creepy and he needs to cut it out, but because I was being nauseatingly nice to him I didn't find that option (that and hadn't realised escape cancelled the conversaion). There were two parts here I found stupid. Firstly - the Agent offering to be made a Joiner to be closer to him. This Agent had just been through mind-control hell and had finally wrested control back, and now I'm meant to believe she will gladly surrender herself to a controlling entity again, and an instectoid hivemind at that. Good on Vector for refusing because that's completely idiotic. It's like her IQ drops 100 points when she enters his pheromone cloud. Secondly - "oooh say something Killiky!" after being married, as if him being part of an emotionless hive of ant drones is some kind of arousing aspect she must constantly be reminded of. "Your electrons are unique" - well hot diggity dang Vector, you'd best get your thorax into the bedroom ASAP!
So yeah. Willing to accept him as a friend, not impressed at the prospect of taking him into my bed.
And quick notes on the other two:
