Breed in the daycare with ditto
Put a male and female Pokemon( must be same Pokemon) in the day care together. Or put a ditto and the Pokemon you want to breed in the daycare.
Ethan/Lyra is your 'friend' during the main story, but you don't really get a girlfriend or boyfriend ingame. The Daycare centre couple talk about it when you first get to the Daycare centre. ....
It depends on what Pokemon you have in the daycare. The Pokemon that hatches from the eggs given to you by the daycare man will be the pre-evolved form of the female Pokemon you have in the daycare.
