Its sorta like this...
First Episode "
Someone is dead at the very start?? I wonder how that happened...."
Nine or so episodes later "
NOOO!!! Mayuri
"
One episode later "So its fate that Mayuri has to die at this specific time... DO SOMETHING OKABE!!"
Couple episodes later "Looks like Mayuri is safe, but at the cost of Suzuha dying in the past now. Looks like we can theorize about someone else going to die since this show just loves to kill off its characters."
