A Stock Phrase
wherein a character acknowledges a past missed opportunity just as they are about to do what they were unable to (or chose not to) all those years ago. Often, the character spared a foe's life in the past and has since come to regret letting the Ungrateful Bastard
live, in which case the phrase usually comes during a Sword over Head
moment and may be accompanied by Prepare to Die
. Bonus points if the character in question is a villain who foolishly killed one of his enemies
in the Back Story
but left their child, now The Hero
, alive out of scorn
, or a Mentor
who couldn't bring himself to kill his beloved pupil
, now the Big Bad
, even when their Omnicidal Maniac
tendencies became apparent.
Note that the phrase may be used in regards to plenty of things other than murder: a risk not taken, a path not followed, a highschool sweetheart not smooched - any of these may provoke the phrase years later, optionally accompanied by a wistful expression and/or a tear in the eye.
This trope can also appear in more disguised forms, without having to invoke the Stock Phrase
. "I have a certain phone call to make"/"there's a family waiting for me"/"I just realised I need to visit an old friend"/etc. are all stock sentences that stem directly from this concept.
