I have been considering that Anna and Daniel had decided these people did not have her best interest at heart and someone found out.............thus bingo they're both dead. It's just too much of a coincidence that they both wind up dead within a 5 month period.
It depends on if their was an onset of sepsis due to the abscess. If not treated, I think you can die pretty quickly from sepsis. What I find hard to understand is how an abscess can get so bad that sepsis developed that quickly and how can anyone determine the number of days?
BUT, are we assuming that the abscess was a result of a dirty needle? I read on CTV that the abscess was in her lung???
