@Luco42 IMO it has to do with the crufixes on their chests. so the sound wave is resonating with the type of metal inside their crufixes and intensifies the wave locally
Leader has 4:58 worth of the drug inside of him, which is 2 seconds below the lethal limit. so its highly unlikely for him to come back.
So yeah he's coming back
Pretty sure the memory loss is a red herring. Leader has shown to have full control over him remembering/forgetting things so I'm pretty sure he's not going to get anymore involuntary memory wipes now.

I noticed that this smile is actually the exact same smile as the one usogui had...
@HyperMuteki probably the same reason that was stated by Kaji earlier. Throwing while the reserved time is lower means you're more likely to recover from death, and you can store any squandered time in your body instead of the hourglass.
@johan its the "squandered time" rule. Basically if D drops the handkerchief at 1 second and C turns at 59 seconds, thats 58 seconds "squandered" and as a result C's heart will be stopped for 58 seconds
