Oh what a goddamn idiot. Akechi's plan had been for the both of them to leave with their horses, rather than Ren scooting over in the horse's saddle. Well at least his arms are lower, he concludes and he has half a mind to just push him off and do this himself, but after a few seconds of stunned, mute and (clearly angry) silence, he snaps the reins forward and the horse starts to make a break for it...well to the castle for now. He has to make them think this is all normal, of course.
