I find her relationship with leon more adorable as well rather than annoyance like albert.
Speaking about the relationship between Ada and Wesker, I can't help but remember how Biohazard 4 was influenced by Luc Besson's film Nikita.
Even one poster is enough to notice it:
And the costume that Albert Wesker wears in this game reminds me of Tcheky Karyo's charactet named Bob:
As in Wesker's case, Bob is the boss whose orders Josephine executes. He has feelings for the spy, which she
may even reciprocate, but there is no intimacy between them, largely due to the specifics of the work and Bob's unhealthy personality.
This is not the dynamic, nevertheless, that we see between Ada and Wesker, but it is still interesting to look at where the roots of certain ideas grow from. I think Ada is interesting to Wesker because she is a very valuable agent, but Ada is too smart and unreliable for this kind of work, so Krauser was right to distrust her.
But speaking of Nikita, I think Ada has a similar character concept. They're both femme fatales and connected to a pretty terrible industry, which doesn't happen without a reason.
In the case of Nikita, she was a drug-addicted member of a criminal gang who participated in a shootout with police officers during an attempt to rob a store. All her partners died, and she managed to shoot one cop. This was the reason why she was sentenced to life imprisonment, but the government faked her death and recruited her into an underground organization, in which she was rehabilitated, but trained to be a professional spy and assassin. She was even given a fake name, that is, Josephine.
And although she has improved as a person and even found happiness with a great man who is kind to her and whom she loves, she is still forced to do terrible things behind his back from time to time, because people leave this business only with a hole in their head.
We see similar traits in Ada's character too. We know she doesn't want to be a bad person, but she is involved in illegal activities. We know that Ada Wong is not her real name, and we also know that her past is hidden because there is probably something to hide there.
And we still don't know her true goal, but it's the driving force that makes her do what she does. Whatever it is, whether it's devotion to some idea or an attempt to pay for the sins of the past, this is something that Leon will definitely stand in the way of. Like he used to do. And that will be the point where Ada will have to choose.
Therefore, I do not believe that their relationship can have a future. This is the law of the spy genre, so even James Bond can't go off into the sunset happy. That's not how things work, because they're kind of doomed to have a tragic outcome. It's kind of a payment for the blood on their hands in a certain sense. Like poetic vengeance. And I'm definitely expecting something in the style of Biohazard 2, when Ada fell off the bridge, only this time without a chance to return. I've seen such an artistic technique before. This is a kind of metaphor for a vicious circle.
By the way, Nikita has an American remake called Point of No Return. Bridget Fonda plays the main role there.
This film could have influenced Ada's image as well:
