He always wonders if it's too dangerous. Really he knows better after his encounter with the Chimera but, no, there's more at stake here than his fears. He can take care of himself at least and he may not find anything in that forest that would be helpful but he has to try. Having no other sounds around him and his own anxiety whenever he takes one of these walks alone makes that whistle sound far more high pitched and loud than Helios would have liked. So he jumps rather apparently too and he whips around to confront the mysterious figure. His breath hitches in his throat some and he moves away slightly. His smile is all but fake as he manages to gloss one over his obvious fidgety features.

"O-Oh. Ah. H-Hello. Lovely, um, night out for a walk isn't it?" Yes he is small talking while standing at the edge of the town's defenses and the terrible forest.
