Gray's protective side comes out when he's with Lucy. Since Lucy can be a bit naive at times, Gray feels the need to safeguard her. At the same time, Lucy's sassiness can keep Gray on his toes.

Juvia might learn to be more open from Lucy, and Lucy might become more understanding of Juvia's deep emotions.

Lucy could potentially teach Naruto about the different types of magic in Fairy Tail, while Lemon could offer her own unique perspective on things.
