From what I picked up watching a recent show she presented with Toby, her son is severely disabled & she herself has a number of health issues.
I imagine that these issues, coupled with the ever increasing pressures of her job are making life not too easy for her. Toby implied as much, in a subtle way, with some of his comments to her.
Therefore, could it just be as simple as, she has decided to listen to the people around her & slow down a bit by stepping away from the incessant pressure & increasing issues of the main Gemporia channel (& Dave “the expert in nothing” Troth’s droning marathons) and give herself the space to breathe & spend a bit more time looking after herself & her family.
