Thorin certainly appreciated the introduction, because it would make it easier for the two of them to converse with one another. And now that he knew for sure that this was one of Bilbo's friends, he certainly did want to get to know the other man. He valued Bilbo's opinion, and therefore any friend of Bilbo's was someone that Thorin would want to befriend as well.
"Bilbo is sometimes too kind" he replied, not sure what the young hobbit might have told the other man. But he did have confidence in his words, because knew that Bilbo often saw the good in people and glossed over the not so good parts. It was one of the things that Thorin loved about him.
