The stairwell. Y/N was walking up with Sheldon as he carried Olivia and Elizabeth's pram.

Y/N: You feel like trying something new for dinner? Maybe Indian, Tex-Mex?

Sheldon: You ever wonder how humans would be different if they evolved from lizards instead of mammals?

Y/N: Okay, let's talk about that.

Sheldon: As you know, lizards, cold-blooded animals, lack the ability to sense temperature. But they do move more sluggishly when it's cold. So, lizard weathermen would say things like, bring a sweater, it's slow outside. I love my mind.

Y/N: We all do. Now, how about dinner?

Sheldon: Oh, I would assume we'd enjoy insects or smaller lizards. We could also pull each other's tails off and grill them, they'll just grow back. Oh! My life-size cardboard Mr. Spock is here! I know he wouldn't care for an outburst of human emotion, but, oh goodie, oh goodie, oh goodie. Commander Spock requesting permission to be unfolded.

Y/N: I'll leave you two to it.

The 4A apartment. Penny, Sheldon, and Y/N were all eating in the apartment as Y/N fed the twins. 

Y/N, perched on a folding chair amidst a miniature landscape of baby paraphernalia, was spooning mashed potatoes into the tiny waiting mouths of his twin daughters, Olivia and Elizabeth.

The twins, perched in high chairs like miniature monarchs, were making delighted gurgles and smearing the fluffy white mess around their faces.  Ten months old and already masters of the demanding gaze, they gurgled contentedly, their tiny hands waving like excited starfish.

Penny sat at the small table, her plate piled high with the same roasted chicken and vegetables Y/N had prepared. Opposite her, Sheldon, as always, occupied his designated spot, his face as impassive as a granite statue. His eyes, however, were laser-focused on the twins, or more specifically, their mashed potatoes.

Sheldon: How come they get mashed potatoes?

Sheldon asked, his voice devoid of accusation making Y/N pause mid-spoonful, a faint smile playing on his lips.

Y/N: Because they asked and you didn't.

Olivia let out a high-pitched babble.

Olivia: Gah goo goo! 

It sounded less like a demand for more potatoes and more like a celebratory acknowledgment of the deliciousness. Sheldon narrowed his eyes slightly.

Sheldon: I didn't know you were making mashed potatoes.

Y/N: Do you want mashed potatoes?

Y/N asked, trying to keep the exasperation from his tone. He loved Sheldon, quirks and all, but sometimes... it was like dealing with another, albeit highly intelligent, baby.

Sheldon: No, I'm just asking.

He then leaned towards Penny, lowering his voice to a conspiratorial whisper, though the apartment was hardly large enough for any conversation to truly remain private.

Sheldon: He's so emotional this time of the month.

Penny stifled a giggle, her eyes crinkling at the corners. She reached across the table, placing a hand on Y/N's arm.
