I take it back, I think TS flew to Nashville in her jet on the 31st. I messed up because I had my dates wrong, plus the sighting of Taylor visiting Gigi Hadid yesterday is very unreliable.
July 30: Church Key dinner, TS pictured with other friends, Tom allegedly there too.
July 31: TS and TH go to the gym separately during the day.
July 31: TS's plane flies to Nashville in the afternoon, according to people who were watching it.
August 1: Tom goes to the gym alone during the day.
August 1: Tom flies out of LAX in the evening.
August 2: TS posts a video of her cat from her Nashville home.
All of this makes sense. Then we get this sighting, which messes up the timeline. I saw these photos in a tumblr post, traced it back to the original tweets, and found what is one of the most suspicious Twitters I've encountered. These are the posts... which are literally the only two posts the account has made since it's creation... yesterday.
My opinion is that we can assume the timeline I laid out above is accurate, and the TS visiting GH pictures on Twitter are misdated.
