[@Savo]I'm also in Traverse Town, somewhere in the Second District most likely. 

Raily's probably been here only a short time. Maybe a few months due to the nature of her business. However, I think she might know Ambrose. Maybe even Ashe. He is a mechanic right? She deals with 'tinkering' too, when she is not busy with helping out Squall and his gang of defenders. Since he's a bit of an oddball, she might've consulted him about things here and there. Thinking he is interesting at the very least, or just to see his opinion on one of her inventions.
