Thus, the includes a sexual protocol:

Know each other’s strengths (she’s a crackshot; he can pick any lock) and weaknesses (she freezes around infected; he can’t swim). Drill escape plans, first aid, and silent retreats until they’re muscle memory. In the end, the couple that fights together survives together.

True apocalypse lovers don't have candlelit dinners. They have a bottle of iodine tablets and a shared sleeping bag behind a reinforced door. That is intimacy.

When you find your apocalypse lover, you experience a high that no drug can match. It is the safety of knowing that if the world turns to fire, you are not facing it alone. You have your ride-or-die in the most literal sense of the word.

Never both be down at the same time. If one fights, the other guards the exit. If one sleeps, the other watches. Split roles, swap often.
