Even if hypothetically Devon does find out Maul had a hand in killing Daki chances are she will still stay with him irregardless
I am a lifetime author one which can very much so eaisily see the threads a skilled author like Filoni leaves for us. I am of the belief a few things will happen in the coming season. A. Devon and Rylee will start showing signs of being more than friends as it was set up they could get together. Devon will probably become extremely protective of him when they go on missions. Rylee already checked her out which is a thing men only do when they like a girl. And Devon went out of her way to ask about him showing she potentially thinks he is handsome. But who knows. That can mean many things in all fairness.
B. If she does find out what Maul did it which is unlikely (later) she almost certainly will stay with him. This does a few things effects Mauls arch of becoming more moralish person in realizing she actully cares about him. Also look at it from Devon’s POV. She had no one left to turn to. Maul is the only man in the galexy who can train her. The Jedi are functionally extinct. Maul is the only one who can give her the power she needs to take revenge on the empire.
Look at it like this, Daki was dead regardless, no way in hell would Vader just allow him to live. Him not force pushing him would likely have not made a difference. So she can rationalize it. “Yes Maul killed my former master however he was already going to die and he only did it to deepen my connection to the dark side. Plus who else in the galaxy can train me at all. He is all I have left.”
Overall I have a writers intuition so to speak she isn’t going to find out next season or possibly the one after that. Such revelations are best saved until the series has a healthy length. Which of course is what the majority of good authors do. It adds weight to the revelation . Filoni knows what he is doing I am extremely confident he will see the path laid out before him. Maul being highly manipulative could say something like “The only reason I did that is because that is how my former master treated me in my youth.” Which would ease tensions
Overall I believe the smoke was a red herring. Firstly he ran into a wall of blaster fire when means ☠️ 99.8 percent of the time. Secondly if you were paying attention he kneeled down in the fog which is what dead men do on the battlefield. And third logistics, it makes no sense at all for him to find them at all given how low profile Maul is. People in the criminal underworld like Maul do not attract attention to themselves. So there is no trail to follow
So overall my gut instincts tell me she is with Maul ride or die no matter what. If she wants revenge she as no ulterior options. Mauls to important a resource to be expended, Devon’s smart enough to figure out Daki was a dead man. Your thoughts? I also believe Two Boots and Rylee will come with them but perhaps play a non combative role with missions.
