He didn’t say “If you’re wrong you’re fucked” either, so it’s the same.

He didn’t really need to. “This had better work” or even your parents saying something like “You better not act up in school” is what we call an implied threat.

You were projecting too with TPM, since you said earlier you knew Obi-wan was going to kill Maul. What if he didn’t and he just escaped?

For one I said it that he would beat Maul and secondly, it’s a prequel so there’s a certain level of predictability that comes along with it. Furthermore Maul running away is pretty much accepting defeat. No?
