We wish it never had to be done, but it does. Every mutant is somebody's child. Most of the time, a parent is in the best position to detect the symptoms and administer the Quarantine if it's appropriate. If it comes to that for you, here are some things to keep in mind.

• They're a threat. Not only to you, but to any healthy children you have, to other family members, to your neighbors. This is undeniable.
• They may love you, but that doesn't change the fact that they're no longer human and you have to do what is right.
• Quarantine protects everybody, and is in the best interests of everyone, INCLUDING the one Quarantined. It saves them from future suffering, from fully becoming the monsters they're destined to be.

Some suggestions for when the time actually comes to Quarantine:

• Telling the child beforehand is usually a mistake, only working occasionally with very young children who trust you without question (this state will not last). Do it without warning, show no sign of your stress or worry. If they tell you (or they know you've discovered) they are a mutant, pretend you accept them for what they are and will love them no matter what. It's not even a lie. You will still love them. That's why you have to Quarantine them.
• Celebrate the time you've had with your child. Make a special day or event for them. Cook their favorite meals the night before, take them to a special event. Spoil them like you've always wanted to spoil them... it's not only for them, but for yourself too. This is your way of saying goodbyes and making peace. It's like a wake. Your child is still alive, but their life as a human has ended, and you will need to Quarantine them soon enough. It also lowers any suspicions your child may have about whether you'd accept them.
• Do it mercifully. If you don't want to outright poison them, slipping drugs into their food before you do it is a good idea. They won't feel a thing, and they won't be able to resist (remember, with mutants, if they resist, you may be dead).
• If you absolutely can't do it yourself, there is no shame in asking another Final Quarantine member, or sympathetic neighbor or relative, to do it for you. They are your support system, if you can locate or recruit them. They will be a shoulder to cry on, and will help give you the courage you need to do what you must, or to let them do it for you, and help you cover it up from the authorities.
