spoiler: AD will kidnap spencer?

so in the australian promo spencer and ezra are in a bunker and they are running away from someone.

and in the american promo of 7B there was this:

this looks like when cece kidnapped alison and she woke up in radley:

i think AD kidnaps spencer and puts her in a place similar to the dollhouse. the others have to find her and ezra is the first one who will find spencer.

what do you think?
