Just answering questions:
Sorry for any confusion, I hope this clears some of it up.
After TDI Courtney continued on with school
Duncan dropped out and got his GED and started working
He was making trips back and forth between his place (somewhere else in the US, yes, this is in American not Canada) and Courtney's
When he left for good he stopped seeing Courtney at all
Seven months have passed with Duncan 'supposedly' being elsewhere and unknowing of Courtney's 'condition'
If you have any other confusions please, please, please ask so that I can clarify them.
