Once at Remus' apartment, he told Sirius to sit down. Remus got up to get some butterbeer, and told Sirius to drink it, knowing it would make the veritaserum wear off. Sirius took a few swigs, and immediately felt his conscience slide back. Now with the ability to speak freely, he burst into tears and knocked Remus over with a hug.
"Thank you so much!" He said over and over again. He felt like he couldn't say it enough.
"Ay Ay Ay! Easy there I can't breath!" Remus exclaimed sitting up on the couch. "So um, how are you?" They continued to talk like this for a while, just catching up on life, Cracking jokes, and laughing there butts off. Once night time settled in, Sirius settled down on the couch, and Remus in his own room.
"Night Padfoot."
"Goodnight Monny."
