Well since she has no worries about money (being the sole heirs to the Blackwood money) they could live in the nice part of La Vida. Hmmm maybe she has opened a vet clinic in her house and treats the area's pets (charges those who can afford it and treats the others for free ie maybe the homeless people's animals?) 

I don't know where you live but here in the UK a lot of the homeless have pets that charities and some vet clinics treat for free or no charge. Ash could do the same. What do you reckon, sound good?

Also, maybe one of your char's comes and helps Ash out at the vets? A way of them knowing each other already? Just a thought
