Born Unlucky: Her first day at the hospital sums this up nicely. She is locked out of her brother's house and has to sleep in her car, Joanna pulls her hair (to "see how well she deals with stress"), everyone keeps asking her why she smells funny, "Have you been to a festival?", "What's that smell? Is that...is that mini-cabs?" Sue gropes her arse, she hears Angela telling Martin to do horrible things to "the new girl" (because Mac told her to try being jealous) Guy persuades her to come stay at his flat and so everyone assumes she slept with him when she didn't. And then there's what happens to her during the rest of the series...
It's All About Me: Mac views her as this when she first arrives at the hospital. While it's certainly nowhere near that extreme, she can be quite self-centered, like when Martin was trying to tell her He has a half-brother, she's more interested in finding a way to stop Mac from moving to Sheffield.
NiceGirl: Despite occasional moments of stubbornness or self-centeredness, she's one of the nicer characters on the show and tries to be helpful towards others.
Chick Magnet: He is universally adored, admired, and lusted after by almost everybody at the hospital with little-to-no effort on his behalf. He spends the series being chased down by Caroline, Emmy, Holly and of course, Sue White.
Men Don't Cry: Mac successfully restrains himself from turning on the waterworks, even in the full knowledge that he's dying of an incurable disease and that he'll never marry, have children and live a full life, as a sobbing Martin Dear blubbers out to him.
Nerves of Steel: Mac is usually very composed in dangerous situations, the best example being when he tries calming down a hysterical Guy in the Season One finale.
Nice Guy: His habit of irritating people aside, he is a genuinely kind, compassionate person. He looks after a very-drunk Caroline, constantly steps in when Guy's bullying of Martin goes too far and is generally pretty friendly.
Nice to the Waiter: Mac seduces the dinner ladies with genuine charm and compliments, and effortlessly strikes good friendships and rapport with the janitors.
No Name Given: Dr. 'Mac' Macartney. Lampshaded and unrevealed variously throughout the series, especially when he is looking at his medical test results:
Dr. Macartney: Sometimes I forget I have a first name.
Ax-Crazy: He psychotically beat a dwarf to death with a stuffed heron.
Bad Liar: Most of the time he can't even get to the actual lying stage, and ends up blurting out the truth instead.
Genius Ditz: He is totally useless at basic social interactions and doesn't understand at first what Joanna means when she tells him she's "late" and offers to call her a taxi, but he does work in a hospital and is a consultant.
Heroic BSOD: Has one after Joanna dumps him, leading to him stealing a milkvan.
Kavorka Man: He is known to have had several sexually-charged conquests throughout his lifetime, despite being completely and utterly devoid of personality, looks, charm and even the most basic social skills.
Dr. Alan Statham: Surreptitiously however, I was bringing her to climax with a breadstick...
The woman he stalks at the hospital chapel is obviously repulsed by him.
Sesquipedalian Loquaciousness: He often speaks in ridiculously complicated sentences and vocabulary, and sometimes even resorts to French and Latin just to express himself.
The Unintelligible: One episode has Alan deciding he wants to be part of a council, so asks Sue White for advice. She promptly tells him to get a voice coach because he "sounds like a hysterical child that's swallowed a conker!"
Casanova Wannabe: Martin is the polar opposite of Guy in every way, a relatively unpopular, socially awkward and rather dumb individual who spends the series in totally unrequited love with Caroline. Rachel's pet nickname for him is "Martin Dear, he's so queer!"
Clark Kent Outfit: In the episode where he poses for a life drawing class we see that he's actually rather ripped.
Dogged Nice Guy: Shows elements of this to Caroline, even when he takes her on a date and all she can do is talk about Mac.
Embarrassing Nickname: Common nickname for Martin is "Fartin." He also goes into a very lengthy anecdote to Caroline about how he came to be known as "Titbrain" at high school. And Rachel and Kim refer to him as "queer".
Extreme Doormat: He lets Guy boss him around, belittle him and casually insult his girlfriend with feeble attempts to prevent it. Guy even manages to convince him to drink his piss in one episode.
The Ace: Seems to be this in the first episode, but her more unsavoury personality quirks come into light as the show goes on.
Bitch in Sheep's Clothing: Often subtly undermining towards Caroline and likes being the centre of attention. Her bitchiness gets turned up to eleven after she becomes the face of a TV documentary set at the hospital.
Covert Pervert: Acts all perky and squeaky-clean, but also claims she gets off on "sticking [her] hand up women and delivering babies" and she finds jealousy, "Exhilerating! In-in a dirty sort of way..."
Hello, Nurse!: The director for the TV documentary becomes instantly smitten with her.
Put on a Bus: Dr. Angela Hunter gets what is probably the most generous bus-sendoff ever. That is, until she is later killed off-screen in an unexplained incident with a moose, constituting a Bus Crash.
Comedic Sociopathy: Her hobbies including stalking people, molesting people, threatening to put SPELLS on people and shooting at people with a bow and arrow. She also gives birth to a lion cub, which raises a whole lot of questions that don't need to be answered.
Crazy Cat Lady: She inexplicably has a few scenes in Season 1 riding a camel. She often barks like a dog and once says she will only answer Alan's questions, "In the language of a crow!"
Deadpan Snarker: Like everyone else on this show, mostly towards Guy, Alan and Martin.
Stalker with a Crush: She is this trope. The scene in which she makes a clay statue of Dr. Mac and considers differently sized genitalia is but one shining example. She even steals some of his genetic material while he's comatose to try to impregnate herself with his child. All Played for Laughs, of course.
She even lampshades it at one point when Mac suspects she's the one who sabotaged his other job offer by telling the hospital he was dead, "Oh, well, you've caught me there, I must be the only Scottish woman in creation, it must have been me, lock me up!"
Bitch in Sheep's Clothing: She spends the first series as a bullied, self-loathing, friendless Butt Monkey. By the time the Special rolls around, she is a flashy, arrogant, domineering bitch who eclipses Rachel in social status and positively terrifies the rest. Granted, the last appearance of her before the special, she got knocked out of a window and nobody even noticed.
Extreme Doormat: The HR staff walk all over her (Joanna forgets her name half the time), Kim and Rachel give her stupid advice on how to win Martin (like telling her she "looks better crouched down", leading her to spend an entire day crawling around the office.) and she generally seems to be the only one who actually does any work.
Granola Girl: One episode has her coming in wearing vegan shoes. However, she is informed by Rachel and Kim that gecko is a kind of small lizard.
Bitch in Sheep's Clothing: She claims she wants to be friends with Caroline and is very touchy-feely with her, but immediately calls her "that weirdo Todd" when Mac pretends to choose her over Caroline.
Romantic False Lead: She happens to appear just as Mac and Caroline are about to lock lips. And when that isn't enough to put the brakes on, she pulls a small child out of her sleeve. Caroline often fantasizes about shooting her.
Too Dumb to Live: Kinda, but leaving orange hair-dye in her locker wasn't a particularly smart move with Sue White around.
Romantic False Lead: Works well as this because he's likable enough in his own right, it's just that Caroline and Mac have a strong connection despite Holly's interference. He comes off a bit like a Third Option Love Interest for Caroline (compared to Guy and Mac), but things don't work out.
Tranquil Fury: He does a very good job of keeping calm when Caroline accidentally drops his twelve-year-old Tamagochi into a wine glass on a date.
What the Hell, Hero?: Passive-aggressively calls out Caroline for dating him when it's obvious she's still in love with Mac, but they do mainly part on amicable terms.
Name's the Same: To another Emily Louise Westbrooke, who is merely pretending to be a physiotherapist and is actually a con artist. Caroline is rather dismayed to learn she's got the wrong Emily Louise Westbrooke.
