Rex was so busy backing the Force Adept into a corner that he didn’t even see that the Dark Jedi had thrown his lightsaber at him - let alone notice that its trajectory traced a broad loop around him and that it was now heading directly at the back of his neck. Luckily, even the most sneakily thrown of lightsabers is no match for ears honed for balance and blend by years of choral singing. Rex heard the characteristic thrum of the blade at the last instant, turned a backward somersault over the saber and then leaped sideways, trying to get both Sith in front of him. He reflected idly on how much the two-on-one sucked you had guy on either side of you.
