Scene sequels are what happens after a particular scene ends. If you’ve done your scene right and ended on a cliff-hanger, then you need sort of take a breather and forge some kind of emotional connection. In other words, make your reader care about what’s happening to your character right after you leave him hanging on the ledge.
A scene sequel does three things:
1) Gives your POV character a chance to react emotionally to whatever has happened
2) Gives him/her the opportunity to figure out how to proceed as he/she is (if you’ve done your scene correctly) in a bit of a bind – which is good. It makes your reader worry whether he/she will make the right choice
3) Sets up the next scene by making a decision one way or another
In order to write a scene sequel correctly, you have to also make sure it unfolds in the right order, because that’s the way a normal person reacts. We think emotionally, then stop to reason, consider all our options, and then carry out whatever we decide. Your character is human too (well, if he’s not, then you may be able to change this sequence of events).
1) Your character must react emotionally i.e. cry, beat his breast, chop someone’s head off!
2) Stop and review the facts – this doesn’t mean logically like Spock. It just means he tries to figure out what’s going on
3) Figure out different scenarios as in – ‘what if I did this’ or ‘what if I did that’
4) Make a decision
Think about your character discussing some terrible ordeal she’s just been through with a best friend, or perhaps praying out loud in church – going through the steps of what happened, and then coming to some kind of decision as to how to proceed. That, my friend, is a scene sequel.
Each of these steps don’t need to have the same weight each time. Maybe some times, the character is heavy on emotion, other times it’s trying to anticipate what sort of action she has to take. The only thing to remember is that these steps need to be covered.
