1 Head Death: RIGHT, I HAVE A MEETING WITH THE PARADOX GUYS. I EXPECT THIS CLEANED UP BY THE TIME I GET BACK.
2 Ishmael: How long will that take him?
3 Death of Inhaling Hatmaking Chemicals: 'ARD TO SAY, GUV. COULD BE 'OURS. OR DAYS.
4 Death of Insanely Overpowered Fireballs: OR, HE COULD RETURN BEFORE HE LEFT.

Returning before you leave is generally considered impolite behaviour in most social circles. I don't recommend it for anyone.

But the Deaths aren't beholden to normal cultural standards.
