This is a very short vocal burst built around the single exclamation Gah, lasting just under half a second. The sudden delivery makes it feel abrupt and startled, like a gasp caught before a fuller reaction can form. It works as a quick jolt of disbelief, surprise or mock horror, landing hardest when the moment needs a sound rather than a sentence.
