"Aren't I?" Sirius smiled brightly, sharing a quick knowing look with Remus before his attentions were back on Andromeda.
"I think Remus and I've got all the cooking taken care of and– Oh, buggery." Sirius interrupted himself when it hit him smack dab in the forehead. Andromeda didn't know who Remus was yet. She didn't know he was her future son-in-law. And, as far as he knew, she didn't know about them. "I forgot to introduce you. Andromeda, this is Remus. Remus, Andromeda."
Sirius waited for the awkwardness to ensue so he could break it.
