And which way to show it dramatically? using oblivious third people in order to terminate his father and occupying the power afterwards, due to his history and exceptional charisma. It would be a masterpiece that would make Tarquin really proud of him.

As seen during the comics and with all the issues about his family he is starting to become merciless, even though it can be considered wisdom.
There is as well, this small reference of a "detect evil" check on him, saying "still not evil", that left me thinking.

So yeah, my unprovable theory is that Elan will make a twist to the dark side.
That's not unprovable; that's debunked before you started.

Elan has shown no inclination to "occupy the power afterwards." Ever since he realized what his father was he resisted at every turn up to and including Tarquin falling from the airship.

He has shown zero inclination toward mercilessness. He had to be almost dragged away from helping Julio on the ground and wouldn't leave him once they were on the airship, and he knew Tarquin would survive the fall off the airship.

There is zilch about his actions during any of this that would indicate an alignment change is necessary or forthcoming.
