Makarov's Point
Natsu: Gramps, Why did you let her leave fairy tail? Don't you have any care for her?
Makarov: Natsu, you must understand this. Lucy knows what she's doing. We must let her decide for herself.
Natsu: GRAMPS! This isn't fair! Are you saying that you're fine with having your kids fight and having your kids leave you?
Makarov: NATSU! Just let her be! If this is what she wants, who are we to interfere?
Natsu: We are her family! We shouldn't let anything bad happen to her!
Makarov: Natsu, Lucy will be back. Don't worry. We must first let her decide for herself.
Natsu: Wh-What are you talking about gramps?
Makarov: She will soon realize her real family. And we will be here when she comes back.
Natsu: Hmph. I will take her back. I promise. She is Fairy Tail's Lucy! No one could ever replace her!
Meanwhile, Lucy was resting in an inn.
Lucy: Oh Plue. I can't understand what I am doing. Fairy Tail has always been my dream. Why did I leave? Hmm, it will be okay right? I have already experienced joining it. Maybe it's time to join another guild, right?
Plue: Pu-Plue
Lucy: So Plue? What guild do you think we should join? A guild that will accept who I really am! How about Blue Pegasus? Sounds good right? Let's go there now!
