Some people here will probably be able to point to more specifics, but all I can say is that he seems to post a lot of 17 second clips and also seems to be one who is in on the whole dog comm thing. Also, he would always take really beautiful pictures of Air Force One/Marine One and of Trump in the White House, and the vast majority of his photos showcase a reflection of some kind. This always makes me think of the Q drops that say “reflections are important”, “find the reflection inside the castle”, and “think mirror”. That being said, I can’t personally point to anything concrete, but just my gut feeling about his role is that it is significant.
