Pokemon Love

Could somebody please tell me how we tell in Pokemon Black when our pokemon are at least starting to love us? I wish it was like back in the old GBA days when they would start coming closer and closer.

There's a woman in the alleyway city where the third gym is, I believe. She comments about how close your Pokémon is to you, other than that, I'm not sure. You could check google, I'm sure others have asked the same. :p

Do you mean Castelia? ;v)

Yus, sorry.
