Kind Restraints

In many works a character can end up being Not Himself. He or she could even hurt someone, or admit to someone that they are worried they might hurt someone. Sometimes, he or she is just acting oddly enough to give people reason to think that they're crazy and/or a danger to themselves and others. Often, their freedom is taken away by their own friends or allies to keep them safe and unable to harm themselves or other people. This could be by restraint, sedation, or confinement.

This will often happen in a safe location, such as their base or a hospital (or whatever serves as one), and will often result in some fight between the captive and the captor(s). This can result in Breaking the Bonds, or if they gain superpowers it could become a Cardboard Prison. Those keeping them captive may employ some sort of Kryptonite Factor to keep them under control. This could also result in an Unwanted Rescue. If they ask to be restrained, it can overlap with No Matter How Much I Beg.

The character being confined does not need to be willing, and the characters to whom they lose their freedom don't need to be benevolent. However, their confinement has to be for safety, and not for malice or punishment, in order to actually fit this trope.

 * In Sodality, Lex Philippine learns of the latest plot by the Icy Finger to take over key positions in Toklisana's government and become Big Brother. He also notes that they have several sympathizers working as prosecuting attorneys, and that the Sodality is at great risk.  While those in the Sodality who can flee do so in order to defeat the Icy Finger, Sodality members that cannot flee so easily are encouraged to find meeting points with SCALLOP agents and be arrested as quietly as possible, taken to SCALLOP prisons so they will be shielded from their political enemies and able to continue their operations from behind safe walls.  Those without serious criminal records either face trumped-up charges or else are encouraged to do petty things to stage that they are in more trouble than they really are.  The plan works, and most of the captured heroes play along with their "sentences" confident that the guards are secretly on their side.  Since most of those in "Team Caged Dove" are the women, this leads to a (considerably downplayed) Girls Behind Bars situation.

Real Life

 * In the United States, a person can be involuntarily committed to a psychiatric hospital on the grounds of likelihood of harm to themselves or others or grave disability, defined as inability to provide for one's own needs as a result of their mental disorder. Even when a patient voluntarily commits themselves, the environment in a mental institution is such that patients are unable to escape or harm themselves, with the purported goal of helping them get better.
 * Suicide watch in any form, which is basically restricting the watchee, if not outright confining them, so that he or she can't kill themselves. Of course, when this is done with death row prisoners, this veers more into Cruel Mercy territory.
 * This is often common to strap patient to a stretcher when being transported by ambulance for a similar reason as seat belts are for cars. Considering the patient is in a moving vehicle, it's done for safety reasons.
