Half an hour later, they were sufficiently plied with firewhisky. Mary still ended up
topless at one point, much to the delight of Peter, who had wilted when she refused to
snog him on a dare. Alice and Frank were passed out in a corner, but only after
confessing—under Veritaserum—that their shared worst fear was not surviving the war.
Sirius had put his hand on Mia's knee when she paled at that, assuming that she was secretly
afraid of the same thing.
The rest of the group—sans Peter who, too, had reached his limit and collapsed
into a large fluffy armchair in front of the fireplace—began repeating old dares, knowing
each of them would take the Veritaserum instead, finding that digging into everyone's
secrets was far more entertaining than watching Mia give Remus a lap dance at Lily's
amused suggested dare. James mumbled to Sirius that he thought Lily's dares were
uncreative and needed work.
"Who was your first kiss?" Mary asked the group.
"Mia," Remus said fondly.
"Amos," Lily admitted shyly. James was clearly doing his best to ignore her.
"Sirius," Mia whispered, and Sirius's eyes widened just a little at the declaration.
"James," Sirius answered at the same time that James said, "Sirius."
Everyone turned to gape at them. "What?!"
"I don't want to talk about it," Sirius replied swiftly, pouring himself another shot
of the untainted firewhisky as he recalled the moment in question and how he and his best
friend had sworn each other to secrecy about the hows and whys of it.
James poured himself another shot, lifting it in apparent agreement with Sirius's
sentiment while the rest of the group laughed at the sudden discomfort between the two.
It did not last long as Sirius and James toasted glasses before downing their individual
drinks.
Eventually, the dares stopped altogether and the questions turned personal.
"Why did you curse all those girls on Valentine's Day, Mia?" Mary asked with a
smirk. "You've always been clever with your pranks, but that was just... something else."
