What I read about her last text was a reply to a male friend who said he was going to get a haircut and then "broke screen". I have no idea if they mean he literally broke the screen on his phone or what. She is said to have texted back 23 minutes later, "Why?"
I'd like to know that myself. That was sometime during her lunch break. So she had to have been OK for a time unless someone else had her phone and answered the text "for her".
This is correct. It was with a friend of hers.
