Further words aren't needed. Despite appearances, Haku is smart enough to pick up on implications in people's words, especially in his line of work. It means there can't be much in the direction he's heading, but.. turning back now might mean he won't make it to the house before nightfall, not to mention that he sure won't find Eiri if he keeps going back and forth in one spot.

That has almost more priority than survival, really. Survival is only so much as goal insofar it is necessary to find the other. But the thoughts of his Messiah do make another question arose that he just has to ask the other.

"Have you seen anyone else yet?" He doubts there would be so much of a coincidence that this man already spotted Eiri, but you never know. He can't leave any stone unturned when it comes to this - and he doubts it'd be that hard of a question to answer, even for someone who's already guarded.
