Vision/Dream sequence

If Deathstroke were to appear in the Justice League movie, then Zack Snyder would have the honor of bringing him to life for the first time. And since we are talking about Zack Snyder, I can certainly assume that he will appear in a vision or dream sequence of some kind.
I'm excluding the flashback possibility. And that is because it was already revealed that the clip released by Ben Affleck was shot in the Flying Fox, the Justice League jet.
Most likely, Deathstroke's appearance will be, in some way, connected to the Batman. After all, the Dark Knight seems to be, until now, the character that connects the entire shared universe. And he was, after all, one of the best things to come out of Batman v Superman: Dawn of Justice.
So, in this case, this will be just a simple cameo. But did you expect something else? Deathstroke is, as far as I am concerned, a character who deserves to be more than just a secondary villain to Steppenwolf.
