Dracula/Fridge

Fridge Brilliance

In retrospect, having Mina's and Jonathan's son born on the anniversary of Quincey Morris' death in Dracula serves an additional purpose besides just being a sweet coincidence. It means that their son was born, at the very earliest, 12 months after the team destroyed Dracula -- further meaning that, contrary to the ridiculous Epileptic Trees planted in Fan Sequels, there is absolutely no way Dracula is the father of Mina's son.
