Yep, she killed the both of them. I think she wants to bring back some other monster and ask them to be their maid, so she killed the maid and her lover to make it look like they ran away.
Then, after visiting her village, Ivonne will come back with another girl/monster whom she will ask to have as a maid.

that's a bloody maid uniform and bloody brown hat this btch definitely ate those couple!!!
