I see Lee as having a more simple, linear aesthetic than Kara. He want to order everything for their kitchen (aboard Pegasus maybe??) in hardwood with chrome details. Kara, on the other hand, is a more of a mix and match type gal... She prefers all the antiqued, battered-looking pieces. I foresee some sort of argument like this:

K: I don't want a kitchen that looks like a doctor's office, Lee. It's too sterile.

L: It's simple and clean, Kara. There's a difference. I happen to like that look.

K: Well I think you need to step out of that clean and tidy, military-issue box you are in. Join the rest of us in the real world.

L: Come muck around in the muck with you?

(she laughs and shoves page 573 of the Ikea book at him)

K: See that bedroom set?

L: That looks like something my grandmother owned, except it's in worse shape than hers. (Lee squints). It looks like its from a flea market.

K; I happen to like things that are worn in.

L: That so?

K: Married you, didn't I?

(Lee steps closer, leaning in for a kiss)

L: I'll compromise. You pick the bedroom set. I get the kitchen.

(Kara laughs)

K: Fine with me. I have no intention of spending ANY time cooking. But the bedroom on the other hand...
