OH yeah I did not mean for those to happen right away the were meant for down the road. So hmm Maybe an automail engeneer  heard of her reputation and asked her to come look at a client before  the  automail could be installed to  check out the injuries the client sustained. Jiaying could have just finished that  task and deided to  check out the rest of  Rush valley before making the trip home, Since she is from Dublith and Rush valley and Dublith are close  that would not be a to crazy trip for her.
