Bob tries to give the Big Bad the MacGuffin to save Alice, but it turns out that the Clingy MacGuffin has other ideas. It simply reappears in Bob's hand, takes over his body and prevents him from handing it over, etc.
Double Subverted: ... So he captures Carol who just conveniently showed up instead.
Parodied: The Big Bad has Alice. Every single meeting after the capturing has the Big Bad saying something along the lines of "you know, I might be willing to let a few things go if you hand over the MacGuffin" Each time.
Lampshaded: "Let me guess, I have to give you the item if I want her back safely, right?"
Invoked: Bob and the Big Bad are both trying to find the MacGuffin, so the villain captures Alice and keeps her hostage so he will have a back-up plan just in case Bob happens to find the MacGuffin first.
Realising what the Big Bad is about to do, Alice breaks free on her own before the Big Bad can make his demands for the MacGuffin.
