Really? Thats totally my bad, All this time I thought it was Echo 1. Well you learn something new. Sorry again guys and girls.
Easy to miss. No worries. I think the closest they touch on it in the films is the reference to the slime as "ectoplasmic residue". Takes a bit more delving to learn that's a term in spiritualism going back to the seances of the 1800s and was purported to be a manifestation of the etheric realm.
