* '''Straight''': [[QuintessentialBritishGentleman Smith]] develops a strategy in the midst of fighting [[TheDreaded Drake]] despite being scared.
* '''Exaggerated''': Smith calmly performs complicated mathematical calculations in his head to disarm a nuclear bomb that's at ten seconds on the clock while under heavy machine gun fire, with sirens and strobe lights going off around him.
* '''Downplayed''':
** [[TooDumbToFool Smith is too stupid and/or absentminded to recognize threats against him, and thus does not fear anything.]]
** Smith only gets worked up if the situation is ''far'' more serious than what he usually has to deal with. Which given his line of work, [[OOCIsSeriousBusiness is saying something]].
** Smith is visibly nervous, but he is still able to think and reason well.
* '''Justified''':
** Smith is actually a {{cyborg}}, or has endured enough stressful incidents in the past to have deadened nerves.
** A very important part of Smith's training was devoted to develop a fortitude that would allow him to keep his calm even under the most stressful situations; an important skill that professionals in real life, like combat pilots, have to attain in order to excel at their jobs.

* '''Double Subverted''': ...but gets back up, steels himself and carries out the plan.
* '''Parodied''': Drake [[ApocalypseHow brings about the end of the world]]. Smith nonchalantly decides to have a [[DissonantSerenity cup of tea as he watches.]]
* '''Zig-Zagged''':
** Smith is stoic and fearless when facing down Drake's demon army, but runs in fear from an insect on the ground. But that's because [[WeaksauceWeakness he happens to be especially vulnerable to insects of this species]]. But he rebalances his keel and goes back to kill the insect calmly.
** Smith isn't necessarily brave - in fact, he's cowardly at heart and wants to run away - he's just SeenItAll and Drake's army just feels like another tuesday for him.
* '''Averted''':
** Drake summons his ultimate demon, a 200-foot hellbeast. Smith panics and runs away.

* '''Conversed''': "{{This is the part where}} I don't flinch, right?"
