She's not the perfectly patient domestic goddess that everyone thinks she is. It's not that she's living a lie -- she is patient, and supportive, and a fairly calm person, and she loves her husband and doesn't want to be the kind of wife who clings and tries to remake him into her image of what a good husband should be. But she also has a temper, and she gets jealous, and sometimes she feels taken for granted, and sometimes she's so bitter and angry and resentful of Peter's job that she can hardly bear it.

But she also has a firm female support network -- her sister, her mom, her female co-workers -- that Peter rarely sees (and we don't really see either, since we're seeing her mostly through Peter's eyes). And that gets her through the worst days.

LOL, we have discussed this, haven't we? And I know we're on the same page with her. XD

Jones ... uh, I don't think I have a whole lot of headcanon for him! Hmm. I think his relationship with Neal is more distant/wary than either Peter's or Diana's. Peter and Neal obviously have their Thing, whatever it is, and Neal and Diana have settled into a very comfortable, playfully-giving-each-other-crap sort of sibling relationship. But, although Jones likes Neal, he doesn't feel as comfortable with him as either Diana or Peter do.

She was angry at Tenzin for years, and then slowly she began to realize that she's soul-deep glad that things didn't work out between them. She's still more fond of Tenzin than she really wants to admit, but she likes her life (and herself) very much just the way she is, and looking at Tenzin and his suffocatingly domestic family makes her realize that it would have killed her to live like that.

I ♥ Lin so much. And one of the reasons why I love her is because she is (in my head, at least) contented and fulfilled just as she is. Not that she couldn't have a relationship if she wanted to, but she doesn't need a man and a family to make her whole.

That makes a lot of sense to me, though! :D

Hmmmm ... some of my Sheppard headcanon:

Atlantis doesn't talk to him. People assume it does. But that's not what connecting with the city is like. It's not really that different from flying any sort of vehicle, except that it's so incredibly responsive, like a helicopter that acts like an extension of his body. People assume that he has some kind of special connection with the city, but it's more like he has a special connection with everything he flies, and each one is different and unique.

But he doesn't know how to explain that, because saying "No, the city doesn't talk to me" is wrong (it does, in its own way, just like a Black Hawk helicopter does or the jumpers do), and saying "Yes, it does" feels like lying, because he knows that what he means is not what anyone else means. So he just kind of dodges the subject. Rodney, damn his curiosity, keeps asking, but Sheppard's never set him straight because a) see above re: hard to explain, and b) Rodney is wildly jealous because he thinks that Sheppard can talk to the city with his mind while he (Rodney) has never figured out how. Which is entertaining.

Also, Sheppard can't open the doors in Atlantis with his mind, at least no more so than anyone else can. In a city that was built for people with the ATA gene, what would be the point of locks that are designed to be overridden by everyone who lives there? But there are persistent rumors that he can, which he's realized is very useful when he has to get into a room for some urgent security-related reason (sadly, this happens more often than he'd like), so he lets people think whatever they want.

Answered this one on DW - so, copy-pasting:

Sara has a danger-junkie streak bordering on self-destructive. But she's too rational to indulge it most of the time, for one thing because she knows, on some level, that if she allows herself to push the boundaries too far, she could easily keep pushing them until she dies.

This is the impulse that draws her to Neal. The unexpected thing isn't that she's attracted to him, because even she could have predicted that, if she'd looked back over her history of dating volatile, dangerous, sometimes abusive men. No, the unexpected thing is that she really likes him as a person, and they make very good friends. As lovers, however, they are terrifyingly combustible -- the sort of relationship that burns very bright and hot for a short period of time, and ends up with both people getting burned. But the underlying warmth of friendship is still there, which is something she hasn't had in her past relationships. Intellectually, she knows full well that she and Neal don't have a future together -- that it's a casual, fast-burning love affair. But she has this genuine warmth for him, and vice versa, and when they stop trying to be Boyfriend and Girlfriend and just relax, they get along really well (sort of like Neal and Peter get along whenever they forget they're supposed to be on opposite sides). And this is what keeps her from either severing things completely, or very firmly stuffing Neal into the Friend box and leaving him there: because she hasn't had that warmth and mutual affection with past boyfriends. It's just not the sort of affection that leads to a marriage and a house in the suburbs. As soon as they start wanting things from each other, it disintegrates. And yet, she would totally trust him at her back in a gunfight, and if something really devastating happened, like, say, her mom died, Neal is probably the first person she'd call for a sympathetic shoulder to cry on (possibly followed by a 2 a.m. tryst with underwear flung all over the room ... possibly followed after that by a giant catastrophic fight and not talking to each other for a month). It's precisely that kind of weird relationship.

Rodney!

I don't actually believe that Rodney is deathly allergic to all the things he thinks he's deathly allergic to. I don't think that he's lying; I just think it's a combination of hypochondria and possibly having had allergies and/or bad experiences in childhood. And this doesn't mean I can't enjoy anaphylaxis fic; I've read and quite enjoyed it, and even written it myself! But my headcanon for Rodney is that he's not actually allergic to lemons, etc, except perhaps very mildly.

Already did this one on DW. Copy-pasting my answer from there:

He's impossibly jaded and cynical, but he loves more deeply than he'll admit. In some ways he's too smart for his own good -- Mozzie's paranoia and cynicism is, in part, a reaction to knowing a little too much about how the world works, and being able to envision all the things that can go wrong in a given situation. He has a bolt-hole for every situation and a contingency plan for every possible contingency. His backups have backups.

He grew up always believing that he had to be able to let go of anything (money, people, things) at a moment's notice. He envisions himself as a ninja slipping around the boundaries of society, footloose and fancy-free, capable of dropping out of sight instantly if he has to. In reality, though, he's a lot more tied down than he wants to admit.
