According to the website of an unrelated SC attorney,
In order to be convicted of kidnapping the Solicitor's office must prove the following occurred:
an abduction, carrying away, confinement or detention
of a human being
without legal justification or cause
Kidnapping charges may accompany allegations similar to the following scenarios:
locking or holding someone in a closet or bedroom
forcibly taking someone from one house to another location
making someone remain seated or otherwise stay in one place during an argument
detaining someone who is having an affair with your partner
Although kidnapping may occur by force, it can also be accomplished by restraint (such as locking or blocking a door) or by trick or deceit (called inveigling).
There is no requirement that the episode last a certain period of time, even the briefest of detention or holding can qualify as kidnapping under South Carolina law.

It sounds to me like all the solicitor has to prove is that they lured her out of the house and to PTL under false pretenses. The amount of time she was there or what may (or may not) have happened to her after that doesn't seem to be a requirement to obtain a conviction, per SC's definition.
