They were like their own little kids in a way. Though Lucy wouldn't say that - she wouldn't want to step on Regina's toes; after all, Regina was the one that had looked after them for so long. Lucy and Natsu were more like surrogate parents.

She was okay with that. "Heiek!!" Lucy squealed in surprise, feeling his fingers against her ribs. Of course, Lucy being Lucy, figured that it was Natsu being Natsu tickling her or messing with her in general, and retaliated with a poke at his ribs in return. "Take that~!" She giggled.
