"Let her have some time to herself," Sirius suggested. "I'm sure Harry has a lot of
questions, and I don't think he would appreciate me going after her, considering what just
happened."
"That would be accurate," Harry replied sharply.
"And I've seen the lad destroy a Dark Lord, so frankly I'd rather not be left alone
with him, Moony." Sirius tugged on Remus's robes, forcing his friend to follow him into
the other room where he poured a glass of bourbon for himself and two tumblers of
firewhisky.
"Come on, Harry." Remus pushed the crystal tumbler toward him. "Let's have a
drink."
"Send a Patronus to Tonks first to let her know what's happened, then close the
Floo and put up anti-Apparition wards," Sirius instructed Remus. "I don't want anyone
coming in unannounced. The last thing she needs is to be overwhelmed."
"She's already overwhelmed, Pads."
"Well then, I don't want to be overwhelmed."
Remus silently assented and walked into the other room to close the Floo as Sirius
requested. While he was gone, Sirius and Harry sat down, both not touching the drinks in
front of them. When Remus returned, he took a seat at the table, smiling at the genealogy
book in front of him.
"One of you going to explain now?" Harry snapped impatiently. "I have a lot of
bloody questions."
"Drink first," Sirius gestured, finally knocking back a healthy swig.
After taking a deep breath, Remus began, "As you know, when Sirius and I were
children, we had the pleasure of befriending your father." He took a pause, "What we never
told you is that we were both introduced to James by his sister."
"Oh, we've already covered that," Sirius told Remus with a nod. "Got all the way to
teaching him about bonds."
"And Mia?"
"Not... entirely there yet. Harry, I didn't get a chance to tell you that your father's
sister was actually adopted. We didn't know it until years later, but she was a Muggle-born
witch that lost her family. Dumbledore brought her to the Potters—brought her there
because she was wearing a Potter heirloom," Sirius said, giving Harry a meaningful look.
