A robot is made for a specific duty to be done, this was true when Equestria was whole and it is true while Equestria is shattered apart. Ponies can wither and become frail, buildings may crumble, but the cold, lifeless steel will continue to remain.

Pick fears that he has no destiny, no grand fate awaiting him. No adventures to follow, no plans or ambitions set in place, and he fears that his life will forever be boring.

When you wake up for war, you might not wake up in time.

What happens when you die...?
