Sam's hanging corpse and Greg falling
In this film, we see Greg and Cath discover Sam's corpse, hanging where it was before.
Cath then jumps onto the body, and tries to swing across, but then a Crawler gets Greg and he falls down below, which is where Juno fell and into water. I know she had to climb up the wall a bit, and then almost fell but Sarah grabbed her, but as Greg is one of the rescue specialists, even if he doesn't have any gear (can't remember if he did or not) but wouldn't he have had training and at least be strong enough to pull himself up, maybe even better than Juno and climb up to the part where she did?
Because if so, then he could have potential escaped, as like we saw in The Descent, it didn't seem like the exit was that far away (depending on which version you watch, I am from the UK so the final scene in it shows Sarah alone with no way out, but I still believe that there is a way out near that area).
So then, if there was a The Descent Part 3, he could potentially return. I wouldn't care either way as his character was pretty minor and not hugely developed.
But what did you guys think? Did you notice this?
