Kaidan lets his barrier repair itself before he waits for a bit. He can hear the kid approaching; no need to give away his position. Kaidan prepares himself for another fight, quick biotic use even if his L2 is starting to act up, a buzzing in the back of his head that he knows will grow into a sharp, sharp pain. He tosses out a quick push; wide, only to hopefully throw Ken off, give Kaidan the opening he's looking for. Knowing his luck though, they'd do nothing to help him.
