I was reading Thunderslate's 'Into The Fray' when I thought of it. I was disappointed with TWD: Season Three, we never learned what happened to these characters.

Becca looked at the blonde boy who was helping Bonnie refill the machine guns with bullets. He was maybe about her age, wearing a pair of green glasses and a green bubble vest. When he turned his head to tell something in return to Bonnie, a faint green vein pierced through his neck. Even if it was faint and far, Becca could see it perfectly from where she was from.

The teen narrowed an eye, averting her head from it in the slightest.

"Becca," Arrived her elder sister's voice, Shel's. "What are you looking at?"

Said teen looked at her sister. "That kid over there… ugh…"

"You mean Marcello, the omega that whose family Tavia brought here days ago?" Shel asked.

"Yeah, ugh, omegas are so gross." The teen folded her arms. "They smell a lot, they're clingy, and when the guy ones go into their sweat things, they leave that icky stuff behind," Becca explained the last reason with pure disgust, as if she spit a bug out of her mouth.

Shel gasped, cupping her chest. "Becca! How can you say that about someone else?"

"What's the big deal?" Becca placed a hand on her hip. "Roman would agree."

Roman was glad that he was born a beta. That way, he didn't have to worry about digging into a male omega every once in a while. By the time the group released the guy the watchdogs caught, he was sweating, and the group could see the slick that was piercing through his pants.

Shel didn't enjoy that tone of voice coming out of her. "Roman isn't here, though." Shel now resented that man and still did. Somehow, she was sort of glad when that intruder's alpha-friend punched him.

"Honestly, you can't just make odd assumptions about someone else. Just because someone goes into a heat, it doesn't make them a strange person." Shel told her. She had seen the way Becca treated that one girl, Sarah as if she wasn't even there. Other times she'd tell her to go away. Shel had her brows raised at that, but she held her tongue. Somewhere in her heart, she felt pity for that girl with the glasses.

"Then what would?" Becca asked.

"They could be your friend," the woman replied. That word made Becca feel something hard in her stomach. Friend. Friend? How can someone be her friend?

"If you didn't spend so much time telling people to buzz off, maybe you'd have a chance," Shel explained. "And oh, Bonnie's an omega too, you know. What you said could affect her too,"

The woman walked away from her. "I'm disappointed in you,"

Becca's face turned blank, her bottom lip dropping just a little. What did she mean, not spending so much time being rude to others?
