I would really appreciate any advice you can provide, thanks!

there is this woman at the time it was a catch 22, but now the situation is diffrent still verry complicated but diffrent,it should be easy but its not! ok so just to make things easyer for you to grasp i will use letters A B and C, C icing B out and it is because A told C she doesnt know me even though A and B have a long history together but B ran away after saying something regretable, C and B do not know eachother but C is the only way B sees to be able to reconnect and explain the situation and hopfully move forward together with A, at this point in time its been 2 years scine B has come back. it has been 5 yrs scince B said the regretable thing to A, and so B would like some advice on how to get C to give up information about B's where abouts such as the job or even better the address! so its like a triagle hostage type situation sort of. no one is any danger now or in the future i just want to start off with a good old conversation. and they won't let me! can any one help?

You can't make someone talk, unfortunately. I'm a bit confused, but it sounds like B is asking C for information? (After doing some regrettable things?) Has B considered apologizing to C? Often one that's sincere carries a lot of weight. Is there a reason C isn't giving up the information? Can you ask why and maybe do what you can to eliminate the problem?
