It's safe to say Stiles should've seen it coming.
Because adopting a puppy, while dating an Alpha werewolf? Yeah, not a good idea.
They're standing in the middle of Stiles' bedroom, Spunky's big brown eyes looking up at Derek while the Alpha glares at the little pug.
Aw, he's just so adorable.
Stiles can't actually pinpoint who that thought was about.
"So, uh. Derek, this is Spunky. My new puppy, I was going to tell you about him tonight-" Stiles stops himself as Derek's glare turns to him, his everpresent scowl intensifying. "But I see you two have already met."
"We have," Derek says solemnly.
"Isn't he the cutest?"
Derek's wounded expression resembles the one Spunky's showcasing. And it's like-
It's like he's deeply hurt Stiles thinks a puppy is cute. As though up until now Derek was his puppy and now Spunky came along to replace him. Which is completely absurd-
Although.
Huh.
Stiles really should've seen it coming.
He saunters over to his boyfriend, the other's eyes still marred, "Aw, are you jelly, Der-care?"
"Jelly?" he frowns as though he actually doesn't know what that means-
And maybe he actually doesn't? Stiles' gonna need to brush him up on his pop-culture lingo, evidently. Stiles smirks, "Yes, jelly. As in jealous. Of my puppy."
Derek's huff is so not convincing. He'd be a terrible actor.
"You know I love you more than anything else, sugarwolf," he says, batting his eyelashes innocently.
Derek actually, flat-out, straightforwardly, pouts. "Love me enough to get rid of Spunky?"
"Bitch, please."
