When writing a novel, how can a character be developed well, but QUICKLY?

“They are! He broke the rules of the boarding house by petting this character while she was in cat form, so they invoke the ancient rules of single combat via ping-pong, and—”

“Well, maybe if you’d wear more clothes, they wouldn’t feel so cold. Hussy!”

“I’m glad my sex life is so entertaining.”

Is something wrong with my discharge? So, when I masturbate, white discharge comes from my vagina, but it's not stretchy, it's pasty. It doesn't smell and I'm not itchy, so I'm sure it's not a yeast infection. Why is it pasty though?

May pushed Claire’s feet away. Claire rose to peer out the window. “Huh. It’s still there.”

“I know! That’s why I’m putting them under you!”

“I’m serious!” Claire said. “It’s staring straight at me.” She let the curtain fall. “Weird.”

How do you have intercourse with a girl who can remember you for a long time?

“I don’t know. Partying. Going to a pub. Anything besides sitting on the couch reading…” She squinted. “What the hell are you reading?”

“Claire! Why are you still up?”

“You need some tea!”

How does an experienced gay/bi guy handle a bi-courius guy on his first time?

“May! You’re home late! Early, I mean. Well, I mean, it’s early in the morning, but you’re home before I expected. Er, after. Before?”

“Well, maybe if you didn’t spend all day reading—” May prodded the book with its garishly-coloured cover with her foot. “Bizarre comic book porn…”

“So you didn’t meet any cute boys at the club tonight?” Claire called as she bustled about the small kitchen.

What are the core beliefs of liberalism and conservatism? Can you provide a list of defining characteristics for each side?

“Yuuna and the Haunted Hot Springs!” Claire turned the book around.

“It’s a cat. All cats are weird.” May sipped from her mug, inhaling the warmth. She closed her eyes. The room spun. She opened them again. “Ugh. I think I drank too much.”

Create a context between this character and other characters.

Why do I get stressed when I go to bed?

The agent had only one bad thing to say (the synopsis was crap; writing synopses is hard!), but praised the characterization and particularly how well we introduced a character’s personality quickly.

“Cute girls?”

“No way.”

What do you do when your family doesn’t care about you?

“Fine.” May collapsed into the warm spot Claire had just vacated.

“I try not to, but thank you for reminding me. I know I don’t need a cat. I don’t want a cat. What would I do with a cat?”

“None of those either. Look upon the wasteland that is my sex life, and see that it is barren. Naught but a moggie followed me home.”

How do you say "I don't speak Italian yet, but I hope to speak it well one day. It would be a pleasure to learn Italian with you. Would you like to teach me Italian?" in Italian?

May yelped. “Hey! Your feet are cold!”

“I need to do laundry.”

“Exactly.”

“Damn straight. So get to it! This time next week, I want to hear some moans coming through that wall.”

“You know what? Never mind,” May said. “I am way, way too drunk to be having this conversation.”

“But they’re cold!”

Why am I so afraid that gun owners have set traps to kill me outside my house or my car?

They both burst out laughing. “I’m right, though,” Claire went on.

“You don’t need a cat. You can’t take care of a cat. You can’t take care of a ficus.” Claire flopped on the other side of the sofa and wriggled her feet beneath May.

Claire, one of May’s three flatmates, former university roommate, and best friend in all the world, shrugged expansively. “It’s a Saturday night. What else would I be doing?”

Have you ever seen your wife being fucked?

“Claire, I—”

Engaging in conversation that also shows something about their intelligence, personality, wit (or lack thereof); and

“Hang on, are they playing ping-pong?”

“Perv.”

“It’s not looking at you.”

“I’m just a fan of your catch and release program.”

“No, about the cat. You don’t need a cat. You remember what happened to your spider plant, right?”

“About wearing more clothes? How am I supposed to catch any fish if I don’t show off the bait?”

Doing something they enjoy, that expresses their personality, and that is in some way unusual or noteworthy;

After Eunice and I finished London Under Veil, I entered the first chapter in a contest at a convention where you could submit something and have it critiqued by a professional book agent.

“Thanks. You’re looking pretty ratty yourself. Have you been in that bathrobe all day?”

“Exactly.”

“From the look of you, if you try to sleep now, you’ll spend the next three hours hanging onto your bed trying to stop the world spinning. Since you’re not going to sleep anyway, you might as well keep me company.”

“I’ll put the kettle on.”

May studied the black and white comic panels. “Oh, my. She looks…anatomically implausible. What is she doing to that poor man? Wait, are those cat ears?”

“Nope, I mean a cat followed me home. A black cat, to be exact. All the way from the club. Probably still out there, for all I know.”

Claire sat back down, legs tucked elegantly beneath her. “You are looking a bit sloppy,” she said, inspecting May through narrowed eyes.

“Number one, it’s not porn, it’s ecchi, and number two, why would I waste a perfectly good Saturday doing anything else?” Claire pulled at her tea and sighed. “The only thing that could make this day better is if you'd come home with some cute boy, so that after you kicked him out tomorrow I could live vicariously through you.”

In the kitchen, Claire set out a battered pair of mugs: May’s black, with “PEBKAC: Problem Exists Between Keyboard and Chair” in white letters; Claire’s white, with “This must be Thursday. I never could get the hang of Thursdays” in dark blue. She carried both mugs into the living room. “A moggie followed you home? Is this some weird Internet slang I’m not current on?”

“Tart!”

Do that and you can ground your characters quite quickly.

Here’s how we presented the character Claire when she was introduced, which the agent particularly singled out:

“Yep!” Claire chirped. “There’s this schoolboy, see, and he’s homeless, so he lives in this boarding house that used to be a hot springs bathhouse, which is cheap because it’s haunted, so he decides—”

“Yes way. It’s washing itself under the street light. Uh-oh, I think it spotted me. It knows I’m watching it. I swear it’s looking at me.”

“Nary a cute boy in sight.”

“Why is that always your first suggestion? I do not need some tea. It’s three o’clock in the morning! If I have tea, I’ll never get to sleep.”

Essentially, what you do is show the character:
