An alternate version of the promo released earlier this week had a very short clip of Rarity with a green glow in both her eyes and horn. Below the break you can find a link to it over on Youtube. What do you all think it means? Are we going to see some changelings in the finale, or something else entirely? Hit the comments up with your thoughts!
Thanks to Cheezedoodle for the video and iownu142 for the heads up!
