You have committed to sharing information and then after a long wait you have shared practically no information.
Have you seen the written contract between Danny and Ukyo with all the details, liabilities and deadlines? I didn't think so.
Danny has no legal responsibility and has a right to remain silent with zero consequences.
Possibly, though it's nowhere as clear-cut as you think.
You are robbed, and I tell you "The cops won't get your stuff back. The guy who robbed you is staying with me, and i'm working on getting your stuff back. Wait." At this point, i most certainly have legal liabilities. Especially if it could be shown that my promise to "work on the problem" affected your decision to report a crime.
