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

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

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

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

Do you know of a female masseuse that does door-to-door service in Bangalore?

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

“Cute girls?”

“Nary a cute boy in sight.”

Why would my nipples hurt when I touch them?

Do that and you can ground your characters quite quickly.

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?”

Essentially, what you do is show the character:

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

“But they’re cold!”

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.

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

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

“Exactly.”

What do flat Earthers think causes the "magical downward force"?

“Perv.”

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.

“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.”

I'm a 28-year-old guy who has never been in a relationship, nor can I seem to find someone who wants to be in one with me. Why do I feel like a freak?

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

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

“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—”

“I’ll put the kettle on.”

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

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

When did Elon Musk fall from grace?

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

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

“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.”

Well I didn't control myself and asked her for sex ( horny like I Ve never been before) she said that she will think Abt it ,2 weeka went by then she called me ,telling that she reserved a room in a hotel and we meet tonight ,we met,and bruuhh, sex is great , I mean, I had to find a pirstitue ,what I was waiting for to have such a feeling ????, I will never forget that night, I started kissing her she was kissing hard ,she misses sex so bad , she sucked my dick and swallowed my semen ,I felt I'm in a dream , then when fucked ,her ass was very big and the anus was open ,didn't struggle to get my hard cock inside it , she was obviously missing sex , she was shouting ,fuck me yh fuck me , I go fast after every word until I cum , we did that 3 times , then we went to her pussy , using condoms I fucked her so hard the moans were higher , everything was perfect ,in the end I asked her to lick her body , licked pussy ,ass, boobs,then she sucked my cock until we sleeped ,all I know that she was dirty ,well before even having sex with her I knew she is an open minded woman , and a woman that looks that she donesnt know anything , but she knows everything, but never expected having sex with her ,well she was horny and that helped...but no one of us regretted that sex ever.. We still have sex from time to time ,and I started having sex with sex workers , joining threesomes..etc If u want pics of her text me.

“No way.”

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

“You need some tea!”

What are the popular niches to talk about as a content creator on the social media platform?

“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…”

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

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?”

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

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

“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.”

Create a context between this character and other characters.

“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.”

“Exactly.”

“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.

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

“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?”

“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.”

“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.”

“Claire! Why are you still up?”

“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?”

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

“It’s not looking at you.”

“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.”

“Claire, I—”

“I need to do laundry.”

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

“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—”

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

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?”

“Tart!”

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