In a Fairy Tail fanfiction where Lucy showers with Natsu, how would the other guild members react?

The guild would likely be ecstatic. Gray would probably make some snarky comment about Natsu finally growing up, but deep down he'd be happy for his friend. Erza would be all for it and might start planning the wedding immediately, giving orders to everyone in the guild to help out.

Drunk Lucy could also be very argumentative. She might start debates with the more serious guild members like Erza about the silliest things, like whether or not it's proper to eat cake with a fork or hands. This would lead to some comical exchanges as the other members watch in amusement.

Erza would be more composed. She would understand Natsu's reasons to a certain extent. However, she would also see the importance of the guild unity. So she would try to balance between respecting Natsu's decision and finding a way to make him come back if possible. She might send out some members to keep an eye on Natsu from a distance.

The guild members' reactions would vary greatly. Happy, being Natsu's closest companion, would likely be excited about the fanfiction. He might fly around the guild hall, telling everyone about it and adding his own little comments about how accurate or inaccurate it is. He would definitely be protective of Natsu's image in the fanfiction, especially if it's not a positive portrayal.

Most of the Fairy Tail members would not take it well. Happy, Natsu's closest friend, would be extremely confused and sad. He'd follow Natsu around, trying to get him to come back to the guild. Makarov, the guild master, would see it as a huge threat to the guild's safety. He might send some of the stronger members to keep an eye on Natsu and Zeref. And the younger members like Wendy would look up to Natsu so much that they'd be very disappointed and scared for him, thinking that he's making a big mistake by joining Zeref.

The guild as a whole would likely mobilize. Erza would start formulating a strategic plan. She'd consider the strengths and weaknesses of Acnologia and figure out the best way to approach the situation. Gray would also be ready to fight, using his ice - make magic to support the rescue mission. They would all be united in their determination to get Lucy back safely.

Some of the younger guild members like Wendy would be a bit shy about it. They might blush and look away when they see Natsu and Cana together after the kiss. Makarov, the guild master, would likely be more accepting. He would see it as a natural part of the members growing up and forming relationships within the guild, as long as it doesn't disrupt the overall harmony of Fairy Tail.

She would fit in very well. The Fairy Tail guild is all about family and acceptance. Given her parents are Lucy and Natsu, she'd be welcomed with open arms. She could learn from the older members like Makarov and Mirajane, and bond with the younger ones like Romeo. Her magic skills would also contribute to the guild's strength during battles or when helping the town.

One possibility could be that it's a comical situation. Maybe they got into some kind of magical mishap that left them dirty and the only available place to clean up was a small bathroom where they had to share the shower in a very awkward way. Natsu, being his clueless self about social norms, doesn't really understand the awkwardness at first while Lucy is blushing like crazy.

The guild would likely be shocked at first. They consider Natsu as one of their own, so his attack would be completely unexpected. Some members might try to talk him down, like Lucy. She has a close bond with Natsu and would probably try to reason with him.
