Aeon

"She’s like a part of me I can’t let go."

- Leon to Ashley, about Ada, Resident Evil 4.

Aeon is the het ship between Leon Kennedy and Ada Wong from the Resident Evil fandom.

Resident Evil 2 (2019)
In 1998, Leon and Ada first meet while in the parking garage of a dying Raccoon City, amongst the outbreak. As Leon is attacked by a zombiefied dog and struggling to hold it off, a woman shoots the dog off, saving him. The woman comments she’s “surprised he’s made it this far”. She flashes an FBI badge and declares any information to be classified when Leon asks what’s going on, after thanking her for helping him. Leon is soon left dumbfounded and alone as the woman walks off through a door.

Leon leaves for the woman’s direction where he’s met by an imprisoned man. Before Leon can get any answers of him, he’s killed by Mr. X, a tyrant stalking survivors. With the man dead, the woman emerges from the shadows and Leon holds his gun to her, believing her to be Mr. X. Realizing it’s her, Leon tells her he “has no idea who she is,” giving his own name. She tells Leon to get out of the city and then they’ll talk, before again walking away from him; as she does, she says, “Name’s Ada.”

Resident Evil 4
In 2004, Leon and Ada are on separate missions in an undisclosed village in Spain; Leon, to rescue the President of the United States’ daughter, and Ada, to steal a specialized sample of the Plaga held by Saddler. As Leon is getting crushed by Father Bitores Mendez, Ada drops down outside a window and shoots Mendez in the back, causing him to get off of Leon. As Mendez charges Ada out the window, she zip lines up to safety, and allows Leon a chance to escape. Before Leon continues, he can look out the window and question to himself, “Woman in red… somehow so familiar.”

The next time Leon and Ada meet is when Leon exits the castle’s garden. Ada holds a gun to his back and Leon is quick to disarm her of her weapon with his knife. Ada removes her sunglasses and tells him, “Leon, long time no see.” Ada drops the glasses which are to be a smoke bomb as Leon reveals he knows she’s working with Albert Wesker. The bomb goes off and Ada makes her escape out a window. She tells him, “See you around.” She leaves with Leon yelling her name.

Leon and Ada don’t meet again until Leon is on his way for a nearby island in his continued rescue of Ashley, the President’s daughter. Ada is sitting and waiting in a docked boat when Leon emerges through the door. Before Leon has time to stay anything, Ada looks up, telling him, “Need a ride, handsome?” Ada takes them to the island, near a cliffside; Ada informs him she’s got other business and leaves, not before throttling the gearshift of the boat that once she’s out, the boat loses control and Leon slams against the cliffside. As Leon manages to gain control, he comments to himself, “Women…”

Ada throws a paper airplane with her signature red lipstick kiss into the cell room Leon is just about to leave, saying “Perhaps you have fingered it out all ready, but you might be able to get out of here by using the waste disposal vent.”

Sometime later, Leon and his old comrade, Jack Krauser, are engaged in an intense knife fight with Leon on the losing end. As Jack is attempting to stab him through the chest, Ada shoots Jack’s knife away, pulling both men apart. With Ada there, and clearly on Leon’s side, Jack leaves. Once he’s gone, Ada questions if he and Jack knew each other, to which Leon implies yes. Looking for his own answers, Leon asks Ada what she’s doing there at all, but Ada merely walks away, leaving Leon.

Leon and Ada meet up again when Leon starts to succumb to the Las Plaga infecting his body. Ada walks up to him, asking, “Leon, you okay?” Leon struggles to gain back control as Ada moves herself closer to him, reaching out. Leon turns to her and wraps his hands around her throat. Ada is too stunned at first to fight back, but she manages to take a small knife out, stab Leon in the thigh and knee him in the abdomen away. Leon picks himself up and apologizes to Ada, as he takes more suppression pills for the Plaga given to him by Luis Sera. Ada tells him they need to get the Plaga out of his body and Leon agrees, though he needs to rescue Ashley first. Ada tells him fine, and that they need to split up. With that, she walks out the door, leaving Leon alone.

Leon finds Ashley, though is soon confronted by Saddler. Saddler harshly shoves Leon against the chamber Ashley is in. As Leon struggles to stand up, Saddler approaches. Ada fires multiple rounds of her weapon into Saddler, giving Leon time to stand up, rescue Ashley and run out. Saddler mutates and begins heading for Leon again. As Leon is making his way out, Ada attempts the same thing— to shoot Saddler down. This proves futile, so Ada resorts to shooting red barrels, all exploding on top of Saddler, this also proving futile, forcing Ada to come up with another plan to save Leon.

Ada fails as the next time Leon sees her she’s tied up and hanging outside. Leon throws a knife through the rope suspending her above the ground, falling onto a tarp. Saddler mutates again and part way through Leon’s battle with Saddler, Ada throws down a rocket launchers, insisting Leon use it. Leon fires a rocket, killing Saddler. Sadder drops the sample Ada has been searching for. Leon picks it up when Ada holds a gun to the back of Leon’s head, taking it from him. Ada runs and leaps over the edge, landing on a waiting helicopter. She tells he better get off the island before pushing the timer of a bomb, surprising Leon that she actually pushed it. Before leaving, Ada tosses Leon the keys to a jet-ski located beneath the island. As Leon and Ashley make their escape via the jet-ski, Ashley flirts with Leon about doing some “overtime,” which Leon politely declines. Ashley admits she somehow know Leon would and asks about “that woman.” Leon answers, ''“She’s like a part of me I can’t let go. Let’s leave it at that.”''

Trivia

 * Scriptwriter Shōtarō Suga suggests that Leon and Ada had an off-screen romantic encounter while Resident Evil 5 (2009) was ongoing, more accurate, he did say: “romantic dinner/hotel/motel room night”. There was not enough time in Resident Evil: Damnation to explore their relationship as Shōtarō had planned, so he left an “open window” for fans to “interpretate it as they want.” He did confirm that it was somewhere around RE5, and that the line was not a reference to any past games.
 * A common saying from Leon is “Women…”, a saying he picked up after meeting and getting to know Ada.
