The main idea of this episode is about Memory... Scientists can help us recover memories...but why did we lose them in the first place? Inside the tourbus, everyone is sweating...Molly is outside trying to get lemonade, but only gets one for everyone to share because it costs 5 dollars for a cup. Everyone is waiting to get to a hotel, so they can go swimming...They arrive at the hotel to find that the air doesn't work, and that the power is out. They also learn there is a pool, but it has no water in it. Everyone is depressed... The three kids go to their hotel and then leave, to go search for a pool. Clu buys an egg and cracks it on the ground...It steams and cooks in the heat. The gang notices the newspapers are a day old. They find a kid named Cole, so they ask him if there's a pool, and he says theres one close. They go to the pool, but it's filled with green water. The water is slimey and smells. Cole says he went swimming yesterday and it was fine. Fi asks him why he stopped swimming and he said he didn't know...and that he got tired all of a sudden and went home to sleep. Everyone in the town went to sleep at 6:00 the night before...Cole says he usually goes to bed at 8:30 and when Fi asks him why he went to bed at 6 the night before, his head starts to hurt and he says he's ok. Fi thinks that something went on last night... Fi wants to find out more about yesterday, so she asks Irene, the busdriver's wife,She just yells at her and leaves... She asks Ned, the busdriver,he says he stopped...he went out back, and then he got tired and came back. He says he can't remember anything else. Fi asks him again and he replies the same way Cole did...by clutching his head...he leaves. Cole passes out and has a flashback...Everyone is running and screaming at the pool...then it changes to a head bobbing side to side... He wakes up and says "they did something to us". They call Cole's mom and she takes him home... Fi talks to everyone and thinks everyone could agree something weird has happened. No one believes her still, Irene still doesn't want to try to remember, so she asks Ned...He searches his mind and has a flashback of people screaming and running by a park. He then leaves too. Fi goes to the pool to find Jack cleaning it. Jack confronts her and tells her to let go of it...She replies by saying she's just trying to help. Clu later asks Fi if she thinks something happened to his parents and Fi tells him they'll figure it out.At the pool, Ned comes and Jack asks him how he's felling...he says good and that he just can't remember what happened the night before...he just got tired. He doesn't think something strange happened...Jack is cleaning the pool when he hits something...Neither of them know what it is... Fi and Clu go to Cole's house but his mother says he can't come out. taht she doesn't like them putting weird thoughts in his head. The two leave, but Cole comes running after them... he remembered something else...There was a noise, a really loud noise, and then a bunch of green stuff fell into the pool. He remembers more, people running, and then starts to act like he's hurting... He says he remembers a streak of lights when Irene, Ned, and Jack come and tell Fi there was a crash. Irene says she heard the crash... A big smoke, and everyone ran to it...someone was in the smoke, No one can remember the faces... Irene heard someone say it was an accident, Cole said it was like a policemen...Irene added that he said there was no danger... Ned says next they touched them on the head...and thats when they got tired and went to bed. No one saw them leave...Fi thinks there still there...Jack says he found a peice of metal in the pool from the clocktower... So they think the people are in the direction north of them. They run there and see flashing lights, but when they get to a clearing...there's nothing there. Ned and Irene think it's just the heat playing tricks on their minds...they leave. Back at the hotel...The air is back on, and the pool has water again...Everyone goes swimming while FI and Jack talk... He tells her he believes something happens...so they have a "sibling" moment and he pulls her into the pool with him...Back
