After the official 6 released I decided to make predictions of 7's silhouette. (SPOILER ALERT DOWNWARD!!!!) At the end of the episode we see 7's silhouette inside 6's light, I think 6 is showing them the future as her other unique power or 7 is gonna jump out and reveal himself in his episode.
Credits to Mike Salcedo for his Alphabet Lore Series. Note: there is another version of 7 inside the project click "See inside"
