OOOOOOOH OKAY THIS IS INTERESTING. i'm gonna go with the mafia au since we recently started shipping them in it o o p sso i still don't know much about lin, but what i gather is that he's really a critical thinker. he kind of?? gets his decisions from what can benefit him the most, and he generally does make good decisions. he'd not impulsive, like liz is, and he's generally more in touch with himself and can control himself pretty well. elizabeth is.... pretty much the opposite. while when she's in trouble, her mind calms itself down and goes into logic mode, in other times she's not really emotionally stable at all? she puts up this air of sexiness and confidence and loses herself in it, leading to doing things that she'll regret later. lin is kind of an anchor for her. when she thinks about what he would do, it helps elizabeth calm down immensely and rethink her decisions –– plus he's someone she can fall back on if she needs help. because they're so different, he helps her improve and become a generally more put-together/stable person. so i'd say their differences are pretty complimentary –– we'll have to rp them more though, and my opinion on that might change u 0u we'll see!
