It gets better, I just checked out what else she liked on Alice's Instagram. of course it could be that she retrospectively liked things (on Ioan's IG she started liking stuff in August 2018, before they met, but perhaps in his case it was just her getting the job and thus following the shows' lead actor), but it rather lines up well with the timeline. So here it goes.
23rd november 2018: A video of Elsie dancing
7th december 2018: Ella's
best mommy in the world christmas present
14th february 2019: Slow-mo video of Alice jumping from the table (LMAO)
21st february 2019: Alice video about finding a snowflake
15th April 2019: Family picture on the plane
20th April 2019: Picture of Ioan (might I note that there was on the same day a cute selfie on the boat with Ioan and Alice which was the only picture that day she didnt like)
20th April 2019: Selfie of Alice
22nd April 2019: Video of Ioan in London
11th May 2019: Picture of Ioan promoting the 2nd season of Harrow
You see it was very consistent from november 2018 till may 2019 (btw Ioan was also posting occasionally on IG until that exact date too and then never did again until last week except for Michael Apted's death) and then it suddenly stopped completely. There were a lot of couple pictures in that timeframe which she ignored. It might mean nothing, but that's all striking to me. If I had to jump to conclusions she met him in november 2018 (should fit with shooting episode 3 or 4 too where she was an Extra) and then obsessed over him, thus started following his wife. Her suddenly stopping at that certain date (again, exactly the same date as him stopping using socials) could indicate that they developed something (then remotely, because he was in London) around that time (she was still with someone else till summer 2019 apparently). Again, might mean
tit, but it caughed my eye and I was bored LOL
