I wouldn't pair him with anyone, but Vic seems to have a special spot in his heart for Goldie (she loves everyone, of course). I guess it makes sense, since they're neighbors, but I do like hearing him mention her.
Everyone seems to look out for Dizzy, sort of the way you would the baby of the family. Mathilda gives him a hard time about his catchphrase once in a while (poor little elephant comes running up to me, crying), but she also asks me to either deliver something to him or bring him to her house so she can give him a present or item she recovered of his.
Midge talks about Beardo a lot, Kitt and Mathilda have a sibling relationship going on, W. Link and Epona like to chat, which I think is both hilarious (because of the personalities) and cannon. Beardo is trying to regain his status as Head Flirt (he's been a bit off-balance since W. Link moved in), and Roald is too busy trying to beat everyone at all sports to notice anything else.
