In the small coastal town of Talasari, a complex situation has emerged involving four individuals: Chidori, a local fisherman, Emeka, a guesthouse owner, Lilit, a chef specializing in local cuisine, and Morwen, a freelance journalist visiting the town to report on the emerging arts scene.

One evening, Morwen, intrigued by the town's dynamics and keen on interviewing local personalities for her article, decided to visit the bustling fish market. Earlier that day, she had heard from Lilit that Chidori often had the most interesting stories about the sea. However, Morwen had never met Chidori in person, nor seen a photo of him; she only knew of him through Lilit's anecdotes.

Unknown to Morwen, an exchange had occurred that morning between Chidori and Emeka. While they were discussing their respective businesses by the docks, Chidori mentioned to Emeka that he was planning a secret night-time fishing trip to catch a rare type of fish that was thought to be a local legend. Chidori was very specific about keeping this a secret, as he did not want the news to spread and cause a frenzied hunt for the fish, which could disrupt the ecosystem. Emeka, valuing his privacy and having known Chidori for a long time, promised not to disclose this information to anyone.

Meanwhile, Lilit, who had learned from Emeka the previous week about Chidori's special fishing trips, happened to run into Chidori at the market that evening. They exchanged pleasantries, but Chidori was careful not to mention anything about the night-time fishing. At that point, Lilit was still uninformed about the intention to keep the trip a secret, although she suspected Chidori had some fishing secrets he didn't share with everyone.

Later that night, Morwen ended up having dinner at the guesthouse owned by Emeka, who was also a budding chef and sometimes took over the kitchen to test new recipes. As they conversed over dinner, Morwen mentioned her unsuccessful attempt to meet Chidori at the market. Curious about any interesting insights into Chidori's sea tales, she asked Emeka if he might have any stories to share for her article. Emeka, mindful of the promise he'd made to Chidori, avoided mentioning the secret fishing trip but did share other anecdotes he knew would not compromise the secret.

The following day, Morwen coincidentally met Lilit and inquired about Chidori and his sea stories. Lilit relayed the information she had, but also expressed her curiosity about whether Chidori had any special fishing plans that evening, as she had seen him preparing more diligently than usual at the market.

Intrigued by the shroud of mystery around Chidori's activities and aware that both Emeka and Lilit might hold pieces of the puzzle, Morwen planned to approach the situation delicately to gain insight without any of them divulging information they wanted to keep confidential.

Based on the interactions between the individuals:
1. What does Chidori know?
2. What does Morwen know?
3. What does Emeka know?
4. What does Lilit know?
5. Who among them knows the full details of the secret night-time fishing trip planned by Chidori?
Chidori, being the one planning the secret night-time fishing trip, knows the intricacies of his own plans. He's aware that it's focused on catching a rare fish and that he has discussed this plan with Emeka only, under the condition of secrecy. Chidori also knows that Lilit is unaware of the specifics of his night-time endeavor, even though she suspects he has fishing secrets. His actions at the market were calculated to avoid giving away any details to Lilit or others who might have been present.

Morwen, who is an outsider to the local community, has knowledge of Chidori as a fascinating local individual, thanks to Lilit's stories. She knows that Emeka and Lilit have different levels of acquaintance with Chidori, but she doesn't have any specific information regarding Chidori's secret trip. After her dinner with Emeka and her conversation with Lilit, Morwen remains in the dark regarding the full story behind Chidori's secretive fishing trips. Her knowledge is confined to what Emeka chose to divulge, none of which included the night-time trip, and the vague impressions given by Lilit.

Emeka knows about the secret night-time fishing trip because Chidori confided in him that morning. He is aware of the fish Chidori hopes to catch and the importance of keeping the trip a secret. Furthermore, Emeka is conscious that Morwen is looking for interesting information to include in her report but respects Chidori's wish for secrecy; hence, he does not disclose the plan to Morwen. Emeka also knows that Lilit has suspicions about Chidori's unique fishing activities, but it's not clear whether Lilit knows about the particular night-time trip.

Lilit has some prior knowledge, from what Emeka shared with her the previous week, about Chidori's special fishing trips. However, she wasn't told about the specific secret trip Chidori planned for that night. Therefore, her knowledge is incomplete. She detects that Chidori might be preparing for something based on her observations at the market, yet she doesn't grasp the full details, and she doesn't learn anything new from her conversation with Chidori that evening.

Therefore, out of all the individuals, only Chidori and Emeka know the full details of the secret night-time fishing trip planned by Chidori. Chidori, as the originator of the plan, knows about it by necessity. Emeka knows because he was the confidant Chidori chose, and he has kept the information to himself, maintaining the confidentiality of the trip. Morwen and Lilit are both aware there might be more to Chidori's activities than what's visible on the surface, yet neither knows about the secret trip explicitly.
