Lol RD. I think DG started it all with some very odd tweets hinting that she was sad about something. Then other tweets I think from Anna expressing sympathy for DG and Julian. Then Anna seeming to leave gracefully and being able to say goodbye but the others not. Somewhere along the way apparently Carmel has gone too. Resulting speculation about "did they jump or were they pushed." My assessment so far:
Anna- jump
Carmel-jump
Debbie- pushed
Julian- don't know but wish he was staying!
Others may think differently but that's my gleaning of this thread so far.
