I recently replayed the new translation of Chrono Trigger, and I was wondering what people think about this now.
EDIT: Personally, I think that they added the Entity as a setup for a possible sequel. Maybe they had some ideas about CC already. Also, I think that the entity is mentioned shortly before you're set loose to do side-quests, including Mother Brain. I think that Mother Brain being the Entity fits just a bit too well, and I think that that was their original plan to tie up that loose end (in the sequel, which became CC).
