The title sequence in "The Day We Died" was a new gray color, and featured new fringe-science concepts:
- Cellular Rejuvenation
- Thought Extraction
- Neural Partitioning
- Brain Porting
- Temporal Plasticity
- Dual Maternity
- Chaos Structure
- Clonal Transplantation
I'm not sure how Water and Hope fit in with the others, but maybe we'll find out next season!
And of course, the "Observers Are Here" message is still there...
Screenshots of every singe frame of the title sequence can be found at FringeFiles.com.
