I think you're right. I doubt multiple bunches of flowers arrived today due to what she did late last night. They probably were sent when she was all "not okay" over Twitter.She's had those for a while, judging by the state of them. Probably sent to her after her meltdown a few days ago but using them now for a pic because she's a twit.
Echoing what others have said, I too wonder if she knew some scandal was due to break for DW and wanted to get in there first and place herself as initiator for the fallout. And yes she knew she'd be more than on safe ground. Funny how she began referencing sexual abuse and #metoo themes last night out of nowhere. That wasn't anything to do with the bloody books was it.
