Roger is stuck in an abandoned building underwater with Angel. Roger complains when Angel starts to smoke based on their limited air supply. Angel questions how they are going to get out of here. Roger flashes back to three days prior when it all began. Roger headed to the port, having been hired to negotiate the price of fish down. Roger talks to a fisherman who tells him that there are still plenty of fish in the sea, but everyone is afraid of fishing due to a “Sea Titan.” Back in the present, Angel gets more frustrated at their current predicament, wondering if they are going to starve to death. Roger claims they’ll run out of air before then and if she really is an angel she has nothing to worry about. Roger looks at his watch, not wanting to call Big O while she is around. Roger flashes back to three days ago again when he talked to an old fisherman. That night there was a deep fog. Frog-like humanoids with glowing eyes crawl out of the sea. Later, a large number of them jump into the sea. Back in the present, Norman and Dorothy clean at Roger’s mansion. Angel paces around in frustration and due to being hot, removes her jacket. Roger asks Angel whether someone will come after her when she doesn’t come back and she doubts it. Roger spots two large scars on Angel’s shoulders, where wings could have been. Norman asks Dorothy to start dinner for Roger, even though its questionable whether he’ll return. Angel claims that the rumors of there being an unlimited supply of memories down here are all lies. Roger asks why she is looking for them and she says because they’re worth a lot of money. Roger asks Angel whether she was born in Paradigm, as people from this city usually don’t think about such things. Roger makes a jokingly sexist remark and Angel chuckles, calling him a louse, which he says he’s used to hearing. Flashing back to several days ago, Roger headed to a factory of a man named Readerman. Readerman claims he’ll keep building boats regardless of whether fisherman keep going out or not. Roger asks about a unique type of boat he is building. Roger meets with Big Ear at the Speak Easy bar, who tells him he needs something to submerge deep underwater. Readerman shows Roger a pod that can dive underwater, which he built based on some memories he had. Readerman claims it has to be charged first so Roger says he’ll return later that night. Later, Roger spots several of the frog-like humanoids heading into the water. He chases after them but they all jump into the water before he reaches them.
Roger gets changed at his mansion and talks to Dorothy, telling her he won’t need dinner that night. Back in the present, Roger claims he should have eaten before he left. Roger blames Angel for the predicament they are in. Flashing back, Roger had gone to get the diving pod from Readerman but found that Angel paid more for it and already took it out. Roger chases after her and jumps into the pod just as it dives underwater. The pod submerges further underwater, and the two of them can spot many submerged buildings. They head towards one of the buildings that still has electricity active. Several of the frog-like humanoids jump aboard the diving pod. Roger notices that they are actually men in special diving suits and they all let go. The diving pod starts malfunctioning and sinking. Angel tries to open the door but Roger tells her to stop since the water pressure would crush them. Roger pilots the diving pod near the building with electricity and bursts it through to an area where there is breathable air. Back in the present at Roger’s mansion, Dorothy spots Norman struggling with a lot of equipment in his arms. Angel questions what happened to the people who lived here 40 years ago. Roger claims there was a cataclysm. Roger spots several of the diving men below them. They dive towards a bright area on the sea floor where Angel thinks all the memories are. Norman, wearing underwater equipment tells Dorothy he’s heading out. Dorothy says she should go in his place. Once the men approach the light at the sea floor there is a big burst of energy, causing the building Roger and Angel are in to collapse. As Angel flees Roger calls for Big O via his wristwatch. The Sea Titan, a furry Mega Deus sized-creature rises out of the sea, is scaring a fisherman. Roger smashes the window, causing water to rush in. Angel calls him a lunatic but it enables him to get to Big O. The Sea Titan walks onto the shore, crushing buildings as he walks by. Roger gets into Big O and is surprised to see Dorothy in the cockpit instead of Norman. Dorothy claims she doesn’t need oxygen and hence was the better person to come. Roger pushes Big O back up to the surface. Alex Rosewater watches video of the Sea Titan, claiming it is a worthless Mega Deus and all he wants are the memories. He requests the Military Police hold off on attacking. Big O rises out of the water and lets Angel out on the dock. Roger notices the Sea Titan crying out and wonders what it is crying for. Dorothy claims it has lost the master it used to serve. Dastun orders an attack on the Mega Deus but is told they have received orders to not attack it. Dastun tells his men to fire anyway and the Sea Titan bursts aflame. The fur-like material surrounding the Sea Titan is burned away, revealing it to be a Mega Deus. The Mega Deus fires upon the Military Police tanks. Big O jumps in the way and shields the tanks from the attack. Roger prepares for an attack on the Mega Deus. Angel shouts out not to attack its head where the memories are stored. Roger dismisses her, not wanting the memories to be exploited. Big O punches the Mega Deus in the head, destroying it. Angel looks angrily at Big O and walks away.
Another fairly good episode, providing us a bit more storyline regarding Paradigm’s loss of memories while also providing some more character development for Angel. Unlike the Paradigm populace she is obsessed with memories, making Roger and the audience wonder whether she is really from Paradigm. It is also revealed that she has scars on her back in spots where wings may have once been. The Big O fight is one of the shortest in the series, ending after a single punch from Big O. My sole complaint with the episode is that narratively, things jump around way too much between the present and flashbacks to multiple time periods, making it a bit confusing at times when certain events occurred.
