Ive just watched the part you are talking. Yeah it does look odd if you look on the surface what some people saying like "dies in 48 hours, last video 48 volume, even weight 48" But I don't think its anything special.
Reason the claim of died in 48 hours or her body found in 48 hours proved to be false, that was just few hours but rumor spread its 48.
Also the buffering part must have been a malfunction when she uploaded it. Somewhere I got the explanation. When she filmed it, it was fine, when she edited there wasn't any glitch, sometimes the video malfunctions but all the elements as an overlay example the texts, voices remians the same. Also to explain the part the clock jumped to 3 mins, its because she cut some part or fast forwarded, which caused the high pitch voice. And why she didn't edited the leftover buffering part, cause editing is really exhausting. As she wasn't mentally stable, she didn't have any motivation to edit more. So she said in the description which requested to the viewers to skip the glitch.
And some say the high pitched voice was "i will die" which isn't correct either cause she was showing how to apply toner or such and said "rub on my face"
Moreover she was facing bullying for a while so that can be her cause of suicide.
I usually avoid the sacrifice topic cause it lies on the verge of gossips, uncertainty. Moreover, bh might be getting ideas from us to stimulate that sacrifice hints on mvs cause there are more sh*t stuffs they are doing and showing and to avoid other discussion. The storyline sacrifice stuffs I never believe to be true. If something really has to happen with someone, you will see them rebelling or showing distress frequently which isn't present in beeteeass with "butter", they are fully enjoying it and ridiculing in a way to mock us.
