I think there is more to this guy than meets the eye.
Just from talking with him I have a feeling that his character was used in a previous diablo game but he is now in diguise.
He also for me has pretty much confirmed that Leah will return as he found it laughable that my character thought Leah was dead for good. Maybe she will get that inn afterall
Also I may be wrong but is Leah not the heir to the Throne being Prince Aidans' daughter? So she is royalty.
