I like that idea a lot. Seems like she was widowed quite recently, as well, right? All the more reason for the girls to be closer now than perhaps they were before - Zita might be more open to socializing with the Vargas clan these days. Lucia would also be keen to keep her in the family and avoid having two casualties instead of just the one. Strength in numbers and so on.
We could maybe even say the two shops are fairly close by, so it's easy for Zita and Lucia to check in with each other.
