Ooh! I love questions like this!

Okay, so this is actually pretty intricately tied to how I think her meeting with Blue would go. And it’s a little something like this:

Felldyne inhaled sharply and clamped a clawed hand over her (new) girlfriend’s shoulder. Alphys looked over at her, confused, and Felldyne drew her close. “Alphys,” Felldyne said slowly, “can we adopt a skeleton?”

The small, blue-clad skeleton across the field started waving excitedly as soon as he saw them. Stars—actual stars!—danced in his sockets and he grinned broadly, obviously delighted to see them. “…didn’t you already adopt a skeleton?” Alphys asked, earning a glare from Edge.

“Yeah, but he’s an asshole!” That earned a growl. “This one’s adorable!”

“Careful,” Edge cautioned, still glaring at both of them. “He’s already got an overprotective reptile breathing down his neck. He doesn’t require an overprotective fish as well.”

“Huh?” Then Felldyne saw a battle-scarred lizard monster approach the smaller skeleton, chatting amicably. She was short and heavily muscled, and missing one eye. Felldyne grinned and rolled her head and shoulders. Loosening up. “I can take her.”

“Undyne. No.”

“HEY! THUNDER THIGHS! YEAH, I’M TALKING TO YOU! LET’S DO THIS!”

Edge sighed and massaged the ridge of bone between his sockets as Felldyne and Swaphys ran toward each other, both of them shouting. “I knew this was a bad idea.”

(Alright. I had a couple requests to continue this, so—)

“I told you that was a bad idea.”

Felldyne groaned, a bag of ice pressed against her cheek. “Fuck off, gutter-rat—“

“and I thought I told you not to call him that,” Paps said, coming up behind her.

She raised a hand, grinning. “Heya, contingency plan! What’s up!?”

“oh, you know. not much. just another beautiful day on the surface. birds are singing. flowers blooming. and a pair of overly-aggressive morons are beating each other senseless in a public park. good thing rus convinced the cops this was some kind of monster tradition, or you two coulda been arrested. the fuck were you two arguing about anyway?”

“She wants to adopt your brother.”

Paps was silent for a few seconds. “…i’m not sure how i feel about that, honestly.”

“What!? How could you—“ At that moment, Blue bounced over. He took Edge’s hand—perfectly smooth and natural—and pulled him down to kiss him on the cheek.

“Everything settled over here?” Blue asked. “The burgs and hot cats are almost ready.” He turned a concerned eye on Felldyne. “You’re okay, right?”

Felldyne stared back at him with wide eyes. “…stars. You’re so fucking precious. Come here.” She caught him around the shoulders and drew him in, staring deep into his eyelights. “What’s your name?”

Blue leaned away from her, his smile uneasy. “Uh. Everyone calls me Blue, but my real name is Sans.”

“Fuck. You’re so cute I don’t even care you’re a version of that asshole.”

“…You really shouldn’t curse. It’s rude.”

Felldyne’s eyes grew even wider and she took a steadying breath. “How are you this adorable!?” she demanded, almost affronted. “I’m gonna keep you.”

“Undyne!” Edge snapped. “You can’t just keep him!”

“Says who?”

“Says everyone! Stars above, why do I have to explain this!?”

“…gotta say, i would not be okay with that,” Paps added.

“We can be friends though!” Blue added brightly, his smile more genuine. “But you really can’t keep me. Sorry.” He extracted himself carefully, grinning all the while.

Felldyne eyed him, then nodded. “Alright, punk, fair enough. But I expect to see you on Thursday night at my house. The gutter-rat and I run a self-defense class, and a little thing like you needs to know how to defend himself. Deal?”

Blue’s eyes exploded into hearts and he abruptly hugged her before running off. “I’LL DEFINITELY BE THERE!”

Edge watched him go, chuckling. Then he realized that Felldyne was glaring at him. “What?”

“He kissed you. Are you two dating?”

“Yes. Is that a problem?”

“…gutter-rat, if you fuck this up, I’m gonna make you do push-ups for a year.”

Paps snorted and started laughing, while Edge just looked affronted.

This was too cute—I think I need to punch something!
