That seems possible depends on how long we would want to establish them traveling together. Would you prefer that they only know each other a little ( They met on the road to Emon ) or perhaps a are more closely aquanited ( lets say they met in Whitestone and came down to Emon together, I would easily believe that when Kari traveled from the greater Vasselheim area to Tal'Dorei his first stop could have been to Whitestone ( for reasons ) and then from there down to Emon. ) I'm easy either way.
