She had a boyfriend 4 or 5 months ago, maybe it was nearer 6, I don't know. A small LA streamer who QT recognised in Emily's spreadsheet.
The basic principle behind memorising a long number is straightforward, though time-consuming. If you don't think it's possible maybe have a look into it and give it a little try yourself, you will be amazed. Years ago I memorised 200 random items and could perfectly recount the list starting anywhere and going backwards or forwards. What I did was simple and maybe took an hour, Emily spent 10 or 12 hours on stream memorising the number. It wasn't a scam.
