Irish hadn't expected Jordan to return to New York, although she knew it was only a matter of time before he found out what had happened to his brother. Initially, Irish had planned to tell Jordan the whole story if he asked over the phone, and she would have urged him not to come back, as Joseph didn't want that.
While Joseph had always forbidden his younger brother from returning, Irish also knew that Joseph supported Jordan's pursuit of his own career. Joseph never imposed requirements on Jordan and simply wished his younger brother could live a happy life.
However, Jordan came back suddenly without informing anyone.
An hour later, Irish went downstairs to the agreed-upon location, waiting for Jordan.
