Barty shook the offered hand. The immediate warmth with which this man had greeted a perfect stranger made Barty very glad that Gaius had managed to escape Bella's clutches.
He glanced at Regulus as he shook Gaius' hand, wondering whether Regulus would keep the details of his past from Gaius. While he wouldn't actively work to cover up anything - a part of the promise he had made to himself when he had left the Ministry's custody - he didn't want new friendships to be jeopardised before they could be made.
Of course, Regulus didn't know that Barty had seen Bella at work on Gaius, and while the fact he had let Gaius escape eased his conscience slightly, he knew that he should have had the strength to stop her in the first place.
"Nice to meet you," Barty replied. "Busy is good, although I just realised that other than this being an import business, I don't know any details about what Regulus wants me to do."
