Val was trapped under debris -in hall of mirrors.
As was Diane. Rescuer came in with stretcher
-Val told him to take Diane first - which after a bit
of chat between D &V he did.
So Diane got out safely.
Last we saw of Val was her looking up at
a big piece of broken mirror which was
ready to fall and saying something like
" go on do your damnedest to it"
scene closes and next we see is anr
stretcher ( covered) coming out .
Diane was pleased to see stretcher but
distraught when saw it covered.
So I presume the large sharp(.shard)
of mirror had fallen on Val and she had
died of blood loss!!!
