When walking on the Mako Cannon in Disc 2 as Tifa, you can see the name "Sister Ray" printed on it.
However, later on in Disc 2, Elena says "Let's not call it the Mako Cannon. Let's call it... the Sister Ray!"
But it's ALREADY
CALLED the Sister Ray. It's printed on the dang cannon itself.
Continuity errors are fun.
