Someone posted this a few days ago on this board. Scavino's phone and POTUS_Schedule's phone both end in -05.
Would also explain why POTUS_Schedule slightly reworded and then reposted (but not retwatted) Scavino within 6 minutes on 10/31/17.
Oh, and it was the first time P_Sched 1) posted photos and 2) linked to another twatter user.
Sauce on both:
