If Tyson were to end up in a coma, at what point would he want someone to pull the plug on him?
To an extent, it would depend on his injuries at the time. If he were to be rendered utterly redundant to the Moriarty Mirrors or if he would need to be completely dependant on someone else, Tyson would want an out without question.
If his family was in danger and the way to guarantee their safety was ending his life, Tyson would absolutely want the plug to be pulled. Perhaps not as a first option, but when traditionally viable options were off the table, sacrificing himself would absolutely be his choice.
Without others lives at stake and without his capabilities compromised, Tyson honestly doesn’t know when he would want the plug to be pulled. He wouldn’t want to stay like that indefinitely and he certainly wouldn’t want his family holding onto hope.
As a general answer, Tyson would shrug and say to give up once a year had passed with no improvement, and leave it at that.
