How do i get an eevee in pokemon diamond?

Question

i beat the elite four and i havent seen all pokemon but im too lazy to search all pokemon haha but i heard there is another way the get eevee by talking to the guy at the pokemon mansion but when i talk to him he talks about how cool his garden is and doesnt ask any questions like whats in the garden. like his butler doesnt go in the back. i wanna know how the butler can ask me those questions so i can see when an eevee is in the backyard.

Answer 1

You can obtain an eevee in Hearthome city, from the woman in the house next to the Pokemon center, just say yes to her question.

Answer 2

You can get an easy one by talking to Bebe in Hearthhome City. She'd right next to the pokemon center. This is only after you get the national dex though. Same for the mansion. He puts a different pokemon in the garden every day, so talk to him everyday.
