I never got to it because... I have no good reason why not, but Noah was totally planning to kill them both. Probably disguising it as an Indian killing. (Sorry, Indians, but you're getting killed anyway, she's being practical. Jax did not sound completely adverse to the idea when she brought it up.)
So it's entirely possible on its way to moving, the guy in question got killed by 'Indians'. She's seen enough Indian kills (and Jax likely has as well, if Dea would like him involved) that she/they would have made it look good?
