Of course he is, she disappeared for almost 2 days and when she came back her room was clean and the dresser drawers shut. The last time that happened, she had him over and annoyed Peetz with loud sex to be a cunt.
If it had been Nader, she definitely would not have been expecting him. She was disheveled, her room was still a sty, and she was genuinely surprised to hear the knock on the door. Remember, she can't cover her emotions for shit. The reason she disappeared was to avoid sharing whoever/whatever it was with her chat. She waited a couple of days for it to die down then came up with some lame excuse about it being a prank.
She
may have seen Nader on July 4th-5th. Those were the days when she made the last smug, dressed-up videos and made up some shit story about "seeing friends" and "playing board games." Sure, Jan. I would guess that he dumped her for good on the 7th, she "relapsed" hard, and on the 8th she went to the ER. Since then she has confined herself to her room and has been in a downward spiral.
Those bruises are aging, and as
@Pizza Sloth pointed out, they would heal more slowly on a person who is on blood thinners (and is also diabetic). I didn't notice them in any other recent videos, but that could be lighting and angles.
My guess is that wearing the yellow tarp is Miss Haversham cosplay. Showering is triggering, but wearing that magical (dirty and wrinkled) dress again is soothing, because she can fantasize about him ripping it off of her. She is more comfortable around filth.
This is all speculation, mind you, but for a boring person she leaves an interesting breadcrumb trail and it's fun to try and follow it.
