Kisame instinctively engaged his Byakugan, scanning the scenery for threats even as he signaled for the others to enter.  It would be normal for Miya to take point and himself to walk rear guard.  It's pretty much impossible to sneak up on someone with all around sight, after all.  He hung back a couple of paces more than usual, getting an odd feeling.  Perhaps it was simply left over from the engagement a few weeks before.
