Star Wars The Last Jedi: John Boyega (Finn) tease scenes “frustrating”

On his Instagram account, John Boyega has teased to have shot scenes “frustrating” for Star Wars 8. Does this have a relationship with his secret mission?
Let us be patient! If we have to wait another nine months before discovering the new adventures of Rey, Poe and Finn, we should have some clues in a month, when the Star Wars Celebration takes place! Well, we certainly will not have to rely on revelations as important as the identity of Rey’s father, but we would be content with anything after all, right? Meanwhile, John Boyega , alias Finn, is rather nice and decided to still teaser a little something on his account Instagram. The actor has indeed shared a photo where we see him in front of a Star Wars poster that represents him himself, taking his head in his hands and shouting, with below, writing the word “Bio-hexacrypt” ! In legend,
Apparently the Star Wars 8: The Last Jedi dialogues have given the 24-year-old a tough time, especially the word “Bio-hexacrypt” . And we understand! Already, the word is difficult to pronounce, and in addition, it seems to be rather complicated to explain! But above all, this raises another question: does this word relate to Finn’s dangerous mission ? According to MakingStarWars , the latter was going undercover on a First Order ship , more precisely on one of those mortals Super Star Destroyer, in order to destroy it from the inside by planting explosives. What if these explosives were called “Bio-hexacrypt” ? Hopefully the first teaser of Star Wars 8, In which Finn should appear alongside Luke and Rey , gives us more clues about it! And you what do you think ?
