For all we know, Maleficent reunited with Lily and told her everything then Lily meets with Emma. That's what we do. :-)  And your theory is just as valid as many others that have been posted.

Though in all honesty, it's not usually based on JUST the 30 seconds of Promo. There are tweets from the actors and the producers, interviews posted, BTS pictures, and various other "spoilage" that starts the theorizing long before we ever see the promo. The Promo just reveals additional details that were (probably) not previously known, and some of which confirm or deny previous theories.

Also, a lot of the theories I've seen posted here are the result of not only information on the Episode, but also from examination of the previous episodes and understanding the particular writer's style. While there have been some really out there theories (and I am just as guilty as the next person), there have also been some really accurate guesses (at least regarding the broader strokes). There is a certain amount of predictability in the way that the plots progress, but it is still a fun predictability seeing the exact method used, which is where some of the surprises occur.
