I'd like to hear ideas on how to make the character appear panicky at the beginning and calm down soon, while keeping the lines limited to the thoughts of a single second.
I'm guessing that this is someone thinking about how to defuse a bomb. There are thoughts running through their head and they have less than 10 seconds. That's what I'm getting from this narrative.
I don't think the author should add another paragraph. The narrative speaks for itself.
